Maybe it will ease your mind to know, that many people don't experience any scary stuff during SP, or even the SP itself. I have WILDed many times, and all I get is some totally awesome, out of this world incredible sensations, that are often much more fun than lucid dream itself (at least for me).

Approach the WILD knowing, that you will have happy experience, and most likely you will. And whatever you feel, see, hear - that's all only in your mind. None of it is real and it can not hurt you in any way.

I have read someplace, that scary experience is some kind of a right of passage. To see, if you are worthy. Happy dreams
