Is this bad spirits in AP?

I've been AP few months back and two days ago I tried different youtube music for AP.

I did felt usual vibration in forehead then aftee some long deep breathings I felt my mattress is like occen waves and starting from my feets towards head. It also feel like road roller between my mattess and my body skin touching the mattress. I felt my body hairs touching mattress a strange feeling. Each time the vibration roller type feeling touching my body skin I can feel my body hair touching mattress a strange sensation that I've never felt maybe goosebumps.

Then ended at back of head then move back to center of my back at tailbone. Then slow pull towards ceiling. It was phycial pull. Almost felt like I'm doing it. I can stop it I feel but I don't want to because I want to see what happens next. I was very curious then continously pull make it little painful at tale bone. My lower back stated to hurt a bit. Then suddenly I yawn and it went normal and pull like feeling ended. After it I slept peach fully. I never had such restful body and sleep. Even next 2 days I felt great. No irritation no overreacting no fear no worries of doing work at time etc. So most of overthinkimg and guilt gone.

As per your experiences what was it? Was it Ap or it was placebo effect that my body was expecting something like to be happened and it did automatically just to make me believe that I was expecting to be happened.
