Basically here's the problem

When I attempt to enter SP, I reach every symptom but one. I feel:

-The lead blanket effect
-Hallucinations
-Flashes/Bangs/Whispering
-Surges and prickling
-Lethargy
-Dream Scenes forming
-loss of feeling in limbs

However, I know that I am not truly paralysed. I know that if I try hard enough, I can move. I think this is why I cannot truly enter the dream scenes that I form. The attempt always ends up with me eventually succumbing to growing urges that build up in my arms to make me move.

A few questions:

Should I roll over before I go into sleep paralysis? I've heard this before but I fear that moving will undo my work

How close am I to sleep paralysis?

If I try too hard to keep my mind awake, can this hinder my attempts at entering SP?

Thanks for any help
