All that I can remember of this dream is that at the end of the dream some other people and I were going through recruit-like training of different types/levels, my former male classmate MJ was there, and I remember us going to an old (maybe ancient) dojo where we were going to learn some special techniques from an old martial arts system being taught by the martial arts instructors who still follow the old traditions.
I remember one of the instructors talking about some of the traditions and showing us small wooden structures and small pillows that you had to use a certain way before training and when someone gets injured, and he showed us a way to improve healing that seemed a bit too magical like it probably did not work.
I remember going to the bathroom to urinate, my former classmate MJ, and another man happened to be going to the bathroom at the same time; and I remember urinating first as we talked about how the healing thing seemed like something that probably did not work, and then we continued talking as I washed my hands but I woke up.
This was an interesting and detailed dream that even became semi-lucid or lucid at some point in the dream, but I can only remember a few parts of the dream; which took place in a modern and sometimes somewhat futuristic multi-story multi-purpose windowless building.
This building was like a college, hotel, resort, recreational, maybe medical building combined with: a hotel/dorm/apartment, college, restaurants, clubs, bars, casino, other types of entertainment areas, medical clinic/hospital, and more.
In one part of the dream it seemed that I was on an upper floor in a college part of the building like I was a college student again, I had a large hotel-like room with a television on the wall, and there were some other interesting design aspects to this room that I can not remember.
At some point I went to take a shower, the bathrooms were separate from our rooms, and so we had to go to public bathrooms to use the bathroom and take showers; and so I walked to one of these public bathrooms, which looked a bit futuristic, and it had automatic motion sensing lights to save electricity when no one was using the bathroom.
There was one or two other people using the bathroom and sinks, the shower area was in a separate room with a futuristic hatch-like door that was open, and so I entered the shower room and I closed the hatch-like door even though I was not sure if it was supposed to stay open or not.
There were separate shower areas that each had their own doors that could lock, I had locked the hatch-like door (which was probably a mistake because that meant that other people could not come in to use the other shower stalls), and so I did not lock the door to my shower stall.
The shower area was a bit futuristic and things were clean, I took a shower, dried off, got dressed, and then I took my stuff back to my room; and then I decided to start walking around exploring the building, and this is where I got to see many amazingly detailed and unique areas.
The dream was pretty realistic as I walked around reading signs outside of various areas that let you know what they were for, I heard music, talking, laughing, and people having a good time in various areas; and I walked into some of these areas, which were mostly entertainment and eating and drinking areas, but I probably walked by the medical area as well.
At some point in the dream the dream went semi-lucid where I probably knew or partly knew that I was dreaming, I did not try to control the dream at all, instead I continued to walk around exploring to see if anything changed; and to see all the many details that my mind had somehow put together.
To my surprise things were the same, signs were still readable and said the same things, different areas were still in their proper locations, people were still enjoying themselves and acting realistically, and the dream felt even more real now that I knew or partly knew that I was dreaming.
I was extra curious to see how dream character acted so I walked around slowly, sometimes stopping inside places, to watch and listen to people; and things were realistic like these were real people with real lives, and they all had different appearances and personalities and things to say to each other.
It was amazing how stable the dream was, it was so stable that it felt real and I even had some of my senses, it was like being somewhat in the future or in another dimension instead of a dream; like I was in a real place.
At some point after exploring, watching and listening to people, talking to some people, et cetera I went back to my hotel-like room to relax and watch some television; and to enjoy the unique design of the room, and I laid on a bed or sitting area near the wall and under the television.
I am not sure if I went to sleep or not but something strange happened where I was now seeing things like I was no longer in the dream, the actress Tilda Swinton was invited to this building by some people who wanted her to star in their film, and so they got her a room in the area where my room was.
They wanted to her to relax and have fun until it was time for their meeting, they hoped that she would say yes to being in their film, and at some point I think that Mrs. Swinton was in her room with someone else when the filmmakers and their security walked into her room for their meeting.
Mrs. Swinton was possibly not interested in being in their film after hearing the details so the filmmakers and their security threatened them, basically holding them hostage and threatening them until she agreed to be in the film, but I can not remember if she agreed or not before I woke up.
