Last night (or actually earlier this morning, I should say), I was falling asleep like I normally would. Something happened (I have no clue what), and I was sort of jolted awake. It was actually more like I was suddenly thinking about nothing and looking at the blackness after I had been lost in thought and drifting off (which is the normal way for anyone to go to sleep). I was seeing a lot of simple hypnologic imagery. It was like colored lights flaming up and forming images I couldn't make out. About 3 or 4 seconds after being half-way jolted awake, I started to get a feeling like I was being shocked. It felt like my heart was starting to beat faster and faster. No vibrations. I wasn't afraid of it, because I knew what was happening. It lasted for a few seconds, went off, and came back on about 10 seconds later. Then it ended for good, and everything went black again. I had no hypnologic imagery or anything after that. I opened my eyes, got up, and did a reality check, but I wasn't dreaming.

I do remember having a non-lucid dream later on about telling someone about the whole experience...

This is the second time it happened. The last time it happened was about a month ago, before I was signed up on here.
