I'm sure the clock is fine. I always sleep with noise in the room and that doesn't prevent me from having occasional WILDs. I don't try to WILD very often. The car might be bad if it is quiet for 5 minutes and then a really loud car comes along. The main WILD i remember having I felt three strong vibrations and then opened my dream eyes and everything was fine. Sometimes people use music to relax. I don't think you are missing anything, WILDing is just very hard for some people.
