Hey, welcome to the forum

That sounds pretty scary man, I'm not sure as to what it could be about. If you want to explore it further but are being stopped by fear, you can remind yourself that you are in a dream and that you cannot be hurt in a dream. Sometimes that isn't enough for me though and I make my body turn invincible or numb or I make my body disappear altogether so that I know I can't be hurt. One last thing you could do to get past that fear is to fill your heart with love and peacefulness, nothing can hurt you when you're like that.

I hope to see you around some more!
