I can move, I just don't.

That it what it feels like for me to be in SP. I've thought about this a lot. I had it normal twice. Loud and shaky and what not. After that, I never even felt paralyzed again.

For me, I just lie there, let my mind wander, listen to music, play out scenarios, do whatever I feel like basically, just not move. I feel more and more relaxed as time passes, then, BAM! Instant relaxed. I feel heavy, in a super-comfortable way, and there was no warning, and nothing special is happening. I never used to notice when this happened, as it is subtle. It's not so much as I noticed when it happens, I just notice it. Then I continue to let my mind wander. Eventually I notice that I am moving, or reading, or can now feel my limbs differently, and conclude rightly that I must be dreaming. It usually fades. Then comes back. Then fades. Then eventually I'm dreaming, lucid, or not. It is still fun and relaxing.

For the longest time I wondered if I was doing something wrong, why I couldn't WILD. Then I realized I was getting into SP, and that even if it wasn't SP, it doesn't matter because I could still move my dream body without moving my real body. After that, I had success.

I hope this helps anyone who might be having any similar doubts. I'll try to answer any questions if there are any.
