Last night I didn't stay up very long. My body didn't feel tired at all, but I decided to go to sleep.

So I lay down in my bed, closed my eyes and didn't move. After a very short time, nearly instant, I began seeing a dark room with a bit of light on the ceiling, which was covered with numbers and signs.
In the middle I remember a orange to red kind of orb.
I started hearing a loud buzzing sound and felt waves of vibration through my whole body until finally I realized I was dreaming.
I can't quite remember the transition, but the loud noise and vibrations made me think of sleep paralysis and I was looking forward to my lucid dream.

I think this is really strange, because after reading hell of a lot about lucid dreaming, one thing gets clear: You can't WILD before sleeping and waking up during your rem period first.

But that's exactly what I did and I'm interested in hearing similar stories or explanations from you.
