As a forward, this happened after 29 hours of being awake, so it was most likely during a rem rebound, it was my 3rd dream of the night (I woke up after the first 2). I was in a house I did not recognize, but my aunt, uncle, and 2 cousins were there. There was an extremely large front window overlooking a jungle and a large river, I could see 2 crocodiles, and my family seemed to be having a discussion on whether they were crocodiles or alligators. After a few minutes I noticed that everything outside the house seemed to be frozen in time (birds were stuck midair, the crocodiles mouths were perpetually open), the only thing that was moving was the sun, which had almost set by this point. I decided to go to bed (in the dream house), and my aunt showed me to my room, it had a large 4 post bed and a large chandelier in the middle. As I laid down, I heard some sort of noise from the far corner of the room, but i thought nothing of it at the time. As was falling asleep (still in the dream) i could hear some guitar playing and thought it might be my alarm clock going off, then out of nowhere this ear piercing scream fills my head, one of the posts snaps off the bed and the chandelier comes crashing to the floor, send glass all over the place. I hear running down the hallway and my aunt comes into my room to ask if I am ok, I tell her that I wasn't hurt, just freaked out. As I stepped out of bed, my foot came down on a piece of glass, cutting fairly deeply. I decided to go to the bathroom to bandage it, when I opened the bathroom door there was a woman standing there in a navy blue dress, that was flowing even though there was no wind. All of a sudden some force pulls me into the bathroom and a second door opens. There was a massive staircase, filled with decomposed bodies, they were all covered in this sort of grey-green slime, I looked behind me and all I could see was darkness, and the woman in the navy dress floating a few feet back, I had no option but to descend the staircase. As I walked down, the bodies started moving, not in a particularly creepy way, just sort of falling over and stuff, but I checked each face to make sure it wasn't someone i knew. After a few minutes of walking/being pulled down the stairs I reached a door, I was really hesitant to open it, I could only imagine how bad it would be, to my surprise it was an early 20th century home, lit by candles and a fireplace, it was a stark contrast from the cold death feeling of the stairway. I could see 3 beds facing me, each had a man and a woman around my age on them, 2 of the couples were awake, but seemed to pay no attention to me, they were completely focused on each other. I walked past the fireplace to the other side of the room, there were 2 couples asleep, and one woman sitting by herself on the bed, looking scared, but happy to see me. I sat down on the bed beside her, and she embraced me, we lied down on the bed and I fell asleep. I wake up in the room where the chandelier has broken, there is blood on the floor from where I cut my foot, and glass still all over the place, I get out of bed making sure not to cut myself this time. I flick the light-switch, nothing happens. Walk into the hall, try those switches as well, still nothing, I mention my problem with the switches to someone who I cant really see, and all I get is a laugh in response, so I go back to my room and surprisingly, it was completely empty, and the floor had changed from white carpet to hardwood. At this point I do a nose pinch RC and instantly become lucid, I took several deep breaths while holding my nose closed, just to make sure. My first thought was to get the hell out of the house, so I plunged my hand through the floor, and pulled myself face first into it. Once my whole body was through the floor, all I could see was complete darkness, with the occasional swirl of color, I must have been pulling myself through this state for a good minute and a half. Because my relative position in the house I was worried I might fall through into the staircase of bodies, but thankfully when I finally popped out of the darkness, I was in some sort of large drainage pipe, I was instantly swept away by the current, but thinking quickly I tried to fly up into the air. At first the current was too much to overcome, but I eventually managed to get myself out of it, I flew to the end of the pipe and was in the jungle I had seen previously, I could see the house a few hundred feet away, and flew in the opposite direction. I cant really describe what I saw on the sides of river, all the animals looked like 3d representations of impressionist art, I landed beside something that I can best describe as a tiger, but its fur had a soft white glow that seemed to be changing the tigers internal structure, almost as if it was made of liquid. I thought I would try and ride it, but the second I got close to it, it swiped my with its claws and I woke up (for real this time).
