Today at 3:00 pm I attempted to go into sleep paralysis. After doing the 99 breaths relaxation method, I just counted down from 100 regularly then just stopped after that. Then I started making a dream scenario for myself and fell asleep, when I woke up I didn't remember going to sleep nor did I remember anything from my dream (I have to work on regaining my recall). I did a series of reality checks just to make sure I was in fact awake.

So how can I tell when I've entered sleep paralysis? What does it feel like? And what does it feel like to actually go into SP?
