Well, I know how you feel. Once I felt a full blown earthquake in my bed. And I couldn't help but think when I broke off from SP:

"That's what they call a MINOR hallucination?"

Well, either way, now that I know what it is, I'm not all that afraid of it. I did one WILD (by accident. I was attempting MILD, lol) and I skipped all the hallucinations and every side effect of SP and just blinked into a dream.

I was like 'WTF? I was just awake RIGHT NOW, I swear!"

So it's only when I wake up to SP do the halluciantions start feeling...a little out of hand. Natural Occurance, but still scary as hell.
