I went to bed after having slept previously that day, so I ended up hitting REM sleep right away.

I fell asleep and found myself in my bed where I had fallen asleep, playing a game on my laptop. I shut down the laptop, and after having done so I found myself inside another room in my house on my stationary PC, where the same game was being played (World of Warcraft, but that's not important).

Here is where it got creepy. I found out that it was likely that I was dreaming, so I did a nose RC and checked if I could breath through my nose, which I could. I understood that it was most likely a dream, even though it felt 100% real. I ended up turning off the PC, but when I did so I was back in my bed with my laptop still on.

The dream (or nightmare one might say) was pretty much centered around this repeating itself countless times. I got very tired and I wanted to wake up, but I found myself just going back and forth in the same instance of events.

I even felt a creepy presence throughout the lucid dream as if someone was watching me, and I kept doing reality checks to see if I had finally woken up or if it really was a dream at all.

I was more confused than I had ever been in my life. I was questioning reality, and had a feeling that I was stuck between reality and the dream world. That I was going to be stuck there forever.

After this going on for a while, and finally decided to try going out the door of the room I was in. At this point I felt really tired and I could barely stand straight (had to sit down on top of my PC) and my eyes were starting to shut down. I barely managed to crawl over to the floor and I decided to jump out of it, to land in a "happy place" (basically a place I imagined with lots of happy colors and feelings), but I ended up in bed yet again. I got really frustrated after I had done a RC and it confirmed I was still dreaming.

Finally after having done the RC I opened my real eyes. I laid down for a while still in shock of what had just happened, I was just happy to be back in reality.
I looked at my clock and one hour had passed since I fell asleep. I am pretty sure the dream from being aware of it being a dream lasted for at least 30 minutes. 30-60 minutes of hopelessness.

Have something similar happened to anyone else? I am a bit afraid to ever sleep again, I just don't want to experience something similar again.
