I remember part of the end of one dream that reminded me of a combination of one of my past dreams where the former United States president George W. Bush helped investigate a crime, the book The Great Gatsby, the 2013 film World War Z, the book I Am Legend, and the video game Saints Row: The Third.
The dream took place probably late in the evening where a party was taking place in a fictional city that reminded me of the city Steelport in the video game Saints Row: The Third, the party was taking place on the second floor of a store/house next to a sidewalk by a road in a small nice shopping district where people could walk around & window shop and/or drive around, and this second floor reminded me of the building from one of my past dreams where a crime took place & former president George W. Bush was asked to investigate the crime.
The store/building was owned by a man who was also hosting the party who reminded me of Jay Gatsby from the book The Great Gatsby combined with the leader of the Third Row Saints from the video game Saints Row The Third because he hosted a public party or parties every week where he somewhat kept a low profile but not as much as Jay Gatsby, he was rich & he owned several businesses/properties/et cetera making people wonder where did he get all of his money/how did he manage it all/et cetera, he employed many people in the city & many of his employees seemed like they were also part-time bodyguards/gang members/mafia members/et cetera when needed, he always had several bodyguards with him as well giving him more protection than most presidents it seemed, he was well-respected in the community, some people wondered if he had connections with intelligence agencies/governments/gangs/mafias/militaries/royal families/et cetera, et cetera.
The store/building had a first floor where the store was with almost nothing but glass walls/windows for window shopping & lots of sunlight, the second floor was the public floor for parties/gatherings/et cetera which also had a lot of glass walls/windows & a large nice balcony with nice views of the shopping district & city & sky, and there was a private hidden basement floor underground that was the owner’s private housing area that only certain people knew about; but the owner had several/many stores & properties around the city, and so he had various private housing areas to switch between when he wanted.
The party on the second floor had a variety of people but mostly people who were rich & well dressed, even though his parties were opened to the public, but this was probably varied depending on which of his properties he had the party at; and this was the nice local shopping district, and so it could be expected that more rich people would go to the party at this location.
There were many workers serving food & drink & doing various other duties, like I mentioned before most of them looked like they were also undercover bodyguards/gang members/mafia members/security/et cetera like my Dream Security that are rarely in my dreams, and everyone was having a good time eating/drinking/talking/listening to music/enjoying the nice view of the city/dancing/et cetera; and the owner was going around talking to some of the people who knew him (many of them seemed like high-level people in the city), along with his bodyguards who went everywhere with him, and the owner was a very likeable/charismatic/whatever person like Jay Gatsby.
At some point something happened that I can not remember clearly, something happened to a woman possibly involving someone doing something to her and/or chasing her and/or talking with her, and she ran to the balcony; and she either got pushed off the balcony or jumped or fell, I am not sure which, and she died.
The party stopped temporarily in shock/surprise, some police & emergency workers were already there at the party & they asked the owner to help them investigate what happened because he was known to be a great investigator among other things (he seemed to be a jack-of-all-trades type person with knowledge & experience in many areas), and so the owner started investigating the crime scene; and once again something happened that I can not remember, and suddenly people who were vampire/zombie-like started attacking like a virus was spreading & infecting people causing them to change into vampires who acted zombie-like like fast/dangerous zombies.
My guess is that someone or several people approached the woman (probably a scientist/agent with a government/military/intelligence agency/corporation/et cetera and the woman probably worked with them but she probably no longer wanted to work with them, and maybe she either had something they wanted and/or she threatened to warn the owner about the secret experiment focused on him) & something probably happened involving something from the secret experimental program focused on the owner without him knowing it (I will explain this later), whatever happened caused the woman to either kill herself or she was killed (probably killed), and somehow later a virus or something started to spread infecting people who then tried to attack the building while spreading the virus to more people & the infected people seemed to be trying to get to the owner for some unknown reason(s).
The many workers at the party started to pull out hidden weapons & to get assault rifles, and they started to fight the vampire zombies/infected people outside the building; and some of the people at the party started trying to escape while the security fought the vampire zombies, but some of them probably got attacked & infected as well.
The bodyguards of the owner took him to the private basement for safety while he called for backup, for a helicopter, to alert the city/et cetera, to investigate/research what was going on, et cetera; and above ground his workers were fighting hard & well, they reminded me of improved versions of the gang members from the video game Saints Row The Third, but more vampire zombies started coming from further in the city until the security got over-whelmed & the vampire zombies got inside the building.
More security arrived fighting the vampire zombies inside and outside the building but huge waves of them kept coming like on the film World War Z until they even attacked the private basement, and so the owner & his bodyguards started helping fighting; and they fought their way outside to the helicopter.
In the dream at this point it was revealed that the owner was a vampire, so I guess he had been alive for a long time explaining his knowledge/skills/wealth/et cetera, and an unknown/known organization(s)/government(s)/intelligence agency(ies)/military(ies)/corporation(s)/et cetera had been secretly studying him probably trying to find ways to make certain people/themselves immortal/stronger/faster/et cetera almost like a super solider program/make certain immortal people to govern/control the world or something like that probably.
Their experiment went wrong somehow or they were testing it to see what would happen, and things got out of control with unexpected results causing their engineered virus/whatever to rapidly spread creating wild vampire zombie-like people; but they were not the same type of vampire as the owner, they were corrupted vampire-like beings now because they scientists had failed to properly copy/replicate/stabilize/whatever his vampire DNA or whatever, but since they were made from partly from his DNA/whatever they seemed to be attracted toward him.
This attraction was unclear, it was not clear if they wanted to kill him or eat him or what, and it was not clear if he could control them or not; either way the owner & his bodyguards started escaping by helicopter to move to another location to try to find a way to save the city & find the people responsible for this virus/experiment/whatever, but I woke up.
