All that I can remember of the very end of this dream is that I was watching a rough (no music, background sounds, film crew conversations, et cetera) promo / teaser / behind-the-scenes-like video for a futuristic Batman-like movie.
The video started in a dark area that had some lights so there was lighting but there were shadow effects from the darkness as well, maybe an underground parking garage or a normal parking garage or somewhere else, and to me it seemed to take place in maybe the future but I am not sure.
My memory is unclear but I think that a very high-level male politician or businessman or someone who was overweight with light-color skin with gray / white hair wearing a suit had arrived at this building with his bodyguards.
I think that someone gave someone an order to assassinate that man, and then the scene jumped to someone who had a small device that I assumed to be a nuclear weapon (I am not sure why I assumed this), and they were planting the device and arming it I assume.
The person then did something strange that I can not remember where they probably did something to themselves to remove part of their memory of what they did so that they could honestly deny it if they got caught, and I remember a substance falling from them into a metal drain and the substance was like an egg white and egg yolk like this was part of their brain that they let fall out which contained some of their memories.
The camera then followed this person from behind who was wearing what looked like a somewhat futuristic black Batman-like suit with cape, everything was filmed very dramatically and maybe there were some slow-motion effects, and the camera slowly panned up to where you could see the back of the person’s head as they walked.
The person walking seemed to be a man even though you could only see them from behind, there was a sound that seemed to be coming from the back of the mask where the two pointy tips (ears or whatever) are, and the sound was almost like something shaking around (I imagined pecans for some reason 😀 ) as this person walked dramatically.
The person reached a room with better lighting and they took off the mask, and this person looked like (was) my former male classmate DH or him combined with my male cousin EE or I saw both of them wearing similar suits; but I felt that he was supposed to be an alien or something even though he looked human because maybe his eyes looked strange and he had a strange alien-like futuristic hairstyle.
A few angles were filmed, a male director or someone gave some directions, and they filmed a few more angles.
My former classmate DH asked a few questions and they did a few shots of him doing some martial arts moves, and then they started a scene where the actor Idris Elba walked in wearing the same suit and he had futuristic dreadlocks and facial hair and maybe his eyes looked different like he was also supposed to be an alien or something even though he looked human and he looked like an alien futuristic version of his character Heimdall from the movie Thor: Ragnarok.

Mr. Elba and my former classmate DH greeted each other with a kiss on the lips, which was weird, but I assumed that it was some kind of alien greeting because I assumed that they were supposed to be aliens even though they looked human and the kiss probably did not seem romantic.
Mr. Elba’s character seemed to be ranked higher than my former classmate DH’s character, and Mr. Elba started talking to him like he was an officer talking to a soldier that was lower ranked than him.
Mr. Elba told my former classmate DH that he suspected that he had just done something bad, and he wanted to know what he did and he probably mentioned some evidence that said that he was going to possibly try to assassinate that high-ranked man from earlier.
My former classmate DH told him that another high-ranked person gave him the order to assassinate that man, but he had no memory of trying to do it.
I think that the scene ended there, and there was talk among the film crew and they probably practiced some fight choreography and the video ended.
I was surprised and happy that my former classmate DH was going to be in a movie (and maybe my male cousin EE, if he was in the video too in the background, if so he was probably wearing he same suit as them and his eyes probably looked strange and his hairstyle was similar to theirs), and I was going to share this video with others and let them know and I was going to call my former classmate DH to congratulate him but I woke up.
This dream was more detailed and clear but I possibly messed up on some parts when typing it, and I did a bad job of describing it here.
The end,
