First of all, check out this thread, it will probably give you a pretty good idea regarding the topic.

Assuming you are one of those rare people that experiences sleep paralysis on a regular basis, then yes it is possible to take advantage of it and enter in a dream, a kind of WILD. Essentially your goal would be to withstand the hallucinations for a period of time, remain calm (as not to disrupt your sleep cycle) and let the transition occur (in a way, just like in a normal WILD). Since sleep paralysis doesn't necessarily occur closely to REM (where you're expected to start your most dream-like experiences), this is not a given. I can't help more since I never experienced it in my life, but we have some members around the forum that suffer from this condition I believe, maybe try to reach out to one of them and ask them for tips
