I had started practising meditation and putting myself into trance states with shamanic drumming before bed at night.

Using shamanic drums I would picture my portal/door and go into the underworld. I found my animal spirt guide and went searching. I went to a place where I met an entity that I wasn't sure if they were good or bad. It looked almost like a dark elf type creature. My mind started to drift towards a pretty a dark place and felt this entity was trying to lead me towards a negative place. I immediately felt pulled away by my animal and higher spirit guide.

After coming out of the trance and then trying to fall asleep normally I kept seeing this entity and its intention to corrupt my mind. Ever since this I have been having very disturbed sleep, ideas and anxiety and can't help but feel this entity has attached itself to me and feeds from my negativity for its own enjoyment.

Any help or recommendations would be greatly appreciated

TL;DR - I encountered a negative entity during a trance state that is causing paranoia and anxiety. Need advice
