WILD isn't really scary. DEILD is actually the same and much faster (and also much easier if you are lucky). Remember that you will experience scary stuff only if you think you will.
If you try to WILD or DEILD, there is absolutely no place for fear of SP or HH. Being afraid of waking up is disturbing enough. My problems with WILD often result from this worry.
If you still feel any insecurity, start with a different technique. I wish you good luck and great LDs!
