Him

The first thing I remember is I'm in a strange house and I see the door to the basement. I walk down it with several other dream characters, a group of three. After defending the stairs, I find myself in a labyrinth. This maze is filled with many people who live there but after much searching, we find a large hostile group that is set on killing everyone in the labyrinth.

Our group tries to stop this mob of hostiles, but after a while, we realize that nothing we do stops them. After a while, our group flees up the stairs. I see a large man there who I seemed to assume is my boss. (At this point I thought to myself that I never saw any of these people in real life and it must be a dream but I didn't think much of it)

After asking my "Boss" for help, he seals the entrance to the basement with a thick ice wall. When I yell that the people down there need our help, he simply responds with "It's better they die than one of us"

At this point, I get stuck in a time loop and I'll explain how the dream/nightmare progresses from here. Behind the sealed door is an elevator with a metal sliding locked door to an elevator. Up this elevator is a room filled with "Heroes" a group that my "boss" seemed to be a member of. After 5 minutes after the "boss" said his line, the door breaks down and the lights go out. The entities would then break the ice wall and open the metal locked elevator. Since it was dark, I could only hear the door sliding open and the elevator going up and down. Once the elevator went up and all the "heroes" were slaughtered, a red light would turn on and the enteties would then hunt down myself and one other dream character I was with. I was unable to wake up until I passed both win conditions.
1. The Heroes can't die.
2. Myself and the DC I was with must not get captured or killed.

If one of the win conditions wasn't met (my partner or a hero died), I must be killed. Once I am killed, the scenario resets and I have to come up with a plan before they breach the ice wall.

Time after time, they broke through the wall, I heared the sliding of the metal door and the light turned on, I was cut in half and I was reset. After having dealt with the pain and fear of dying over and over again, I decide to take the lift up myself and see if I could defend it myself. After taking the lift up, I see all of the heroes. I then see something fly above me and realize that the "entities" we're in the elevator with me. I then see all of the heroes get slaughtered. Within the context of the dream, I was their friends so it hurt me greatly to see them die in front of me. I was also lucid at the time and wondered how I could feel for people I never met and didn't exist. After getting stabbed for the last time, I said enough is enough.

When I respawned, I saw a computer with the text "exit". I looked down and pressed "enter". The computer said nuclear launch commencing and I felt great fear. I looked out side and flew through the wall to see a red light flying closer and closer. Dealing great fear, I became completely lucid and remembered the task of the month.

***TOTM***

I quickly flew down to the road, picked up a parked car and carried it into the sky yelling F*CK YOU!!!!

I herd a *boom* as I flew away carrying the car whilst freaking out because I was going to have to suffer death again before I awoke. I felt the blast burn, fold, then disintegrate my body. After experiencing agony for the last time in that nightmare I awoke. I had a ton of trouble falling back asleep so I ended up staying awake till I had to get up.

That was my first lucid nightmare since a long time ago and they are just as scary and infuriating as ever.
