I have a few questions about SP. I've never been in SP, but I've heard that you hallucinate and see things. Is there away to control what you see? I just think that I'll visualize something extremely scary and do something bad.

Also, I feel like I've been doing something wrong while trying to get into SP. I've laid on my bed for about an hour completely still, but I got nothing other than a slight vibration in my legs. I feel the vibration for a long time, yet nothing happens.
