I know this is like the a millionth thread I've posted on this, but I honestly don't know what the hell is wrong with me!

Ok, so here it goes. I decided to have a nap and try having a WILD. I lay down, fell into SP in like a split second. I started visualizing walking up a continual set of stairs to get me into a trance. It worked well. Until, the SP vibrations hit me! That was perfectly fine. But after that, I don't know what the hell happened! I was numb as hell, but my mind was somehow magically awake now? I don't know how to describe it, but after reading about how you're supposed to wait till after the vibrations I did. But then I was suddenly awake again. I wasn't tranced. And I knew that I wasn't dreaming. I had no more HI either. I was just lying there. WHY DOES THIS HAPPEN EVERY TIME?!?!?! I tried a few exiting techniques, but nothing happened. Eventually I just gave up.

This is so frustrating, what the hell am I doing wrong, can someone please help me?
