I was up for over 3 days, and each time I sat down I wanted to pass out. Since I was unable (military training) I was able to go home after everything was done. I immediately laid down in my bed, hoping to enter some sort of a lucid dream (I haven't had one I can control yet). The next thing I know it's 8 hours later and I'm awake again.

I must have laid down for 30 seconds before I passed out. I was trying to focus on keeping my mind awake so I could enter SP, but I don't even remember getting that long.

Does SP only affect you on a WBTB technique? This was on 72 hours no sleep, and I finally went to bed for the first time.
