I used to get SP all the time, hated it and was terrified. You can read up in some of my other posts about it.
Then it went away and was only few and far in between, I actually kind of missed the rush of having the S*** scared out of me now and then. Strange I
know, but it's ones of those few primal instincts that actually makes you feel alive in this mundane world. Sad part is sometimes when I do get it I
wish I didn't.
Anyway as some other people posted, it can help to have lucid dreams, OOBE's, hallucinations (if you like that), succubus experiences...and more.
I've seen all the proper ways posted on how to better attain it, me myself I have grown accustom to sleeping on my back now, so whenever I sleep on
my stomach or side I can occassionally get it. But never on my back anymore.
But anyway, something I didn't see posted was drinking soda or eating some fruit or candy right before bed. Sometimes the sugar other stuff can help
with inducing it.
Lastly, I went through a weird phase where I wanted to get it all the time so that I could attempt to OOBE, but I got paranoid for a while and here is
how: I heard that if you just "let go" and let the hallucination or vision or whatever it is get you, and just accept it instead of fighting the
dread, you would achieve an OOBE or AP'ing. Anyway I was very close one night to giving in and an even worse feeling of dread overtook me, and it
was, "what is I let this thing take me and I just die. That's that, no if's and's or but's, i just don't wake up." So I struggled mightily
and finally fought my way out of it from basically on the brink and point of no return. Terrifying. Anyway, since then I haven't worried about it
cause if it happens then it happens, oh well. And I have actually had success with achieving very lucid states and AP'ing and OOBE'ing. I like to
think that I have a whole plethora of knowledge about it now so feel free to post again or message me with questions / help / or general discussion.
