These Questions can be answered by different info about SP but I've asked to make sure that I understand it correctly

1. So Sleep Paraylsis is the crossover from Reality to the Dream World Right?

2. From I what I read on the SP Tutorial, it is possible to enter SP by just relaxing and slowly breathing with your eyes closed in bed for a certain amount of time?

3. Can you enter SP during a nap? Will that bring you into the dream world?

4. When does SP usually set in? Thus, can you set your alarm to awake during SP?

Sorry for so many questions
