Okay, I've tried to WILD three times so far, but I was unsuccessful. The first two times I took too much time to relax, like 15 min., and 15 more to reach partial sleep paralysis (hand and feet)

The third time, I made some progress, I managed to relax almost instantly, achieved sleep paralysis in 5 min. and after a while, I also felt something weird, as if the bed was spinning. But it suddenly stopped and I woke up (quite dissapointed). I still had a bit of paraylisis, but it quickly went away.

My questions are: is this normal? should I continue using this technique until I achieve a lucid dream? And why can't I see any hypnogogic imagery?

Thanks in advance
