Sleep paralysis doesn't have to accompany hallucinations. And what it feels like is up to your brain. Usually it will feel like a heavy lead blanket being laid upon you because that's what your brain will associate with not being able to move.

Remember, you can't WILD when you go to sleep at night, because you don't enter a dream then. You need to wake up in the early morning, like 3 or 4am and do it then
