This morning I was awake from 2:40 - 4:00.
I am a teenager so this is pretty bad for me, I need my sleep.
Well, as it has happened the last few times I've been unable to sleep for some time, I finally started feeling tired again, and then my favorite, favorite part happened. It reminds me of entering the Animus in Assassin's Creed 1.

After what I think is a "brief" moment of unconsciousness, I become consciously aware and suddenly know exactly what is going to happen.
I suddenly feel my entire body engulfed in a kind of vibration, kind of like a shiver but also like pins and needles. I'm not afraid at all, I love it and it's happened before.
I get sucked into a dream scene, a pier at a blue water river, I stay conscious for a few seconds before losing awareness.

Anybody know what this is? I love it when this happens (minus the unable to sleep for hours part) despite the fact that the lucid dream only lasted seconds. It's happened at least one more time, maybe two or three more times even. Anyway, I'm just telling my story. Any thoughts?
