Ear ringing after waking up

Hey guys! I just had my first LD and it was pretty weird. I was in a third person view with a girl I have a crush on next to me and I was moving animals by pointing with my hand. I don’t recall how it lasted, but I went to sleep at 1:30am and woke up at 2:45am. The scary part was I woke up to a loud ringing in my ear, similar to a flash grenade/gunshot/explosion. I jolted awake and found nothing around me besides normal things. Any ideas of what could have caused this? Sorry if I’m in the wrong thread I thought this would be the best one. The way I induced LD was through binaural beats and isochronic tones.
