This happened to me last night, I was goin to sleep normally but just before i fell asleep (you don’t ussually remember this part this is the kind of time where you arn’t awake but arn’t thinking and are just there) I then suddenly became aware and I felt a massive tingling and waves. I was getting excited and felt really uncomfortable, I had to get up really early the next day so I got up and went back to sleep. It was pretty epic if I wasn’t getting up as early the next day I think I could have gone further.
Yeah, it sounds like you experienced the moment before your body was falling asleep. It’s normal for you to be scared, nervous, or excited when it’s happening.
If you would have stayed calm, and conscious throught the ordeal, you would have likely entered a dream (WILD).
Next time, just relax and go with it.
