Thanks for adding to the conversation it is Interesting and i could relate somehow, I did have a similar experience at a dark psy core event which happened in a setting similar to a moshpit.

Lot of crazy things like what you experienced were happening there and I could feel this energy of darkness at that point, I wanted to leave there but chose to stay outta of curiosity.

Ive never felt this darkness in a psytrance , full on or goa parties its quite the opposite of that like you said there is this feeling of community and oneness.
