I don’t know about revenge but you can extinguish unwanted beings from your vicinity.

When my children were young and got spooked by things I would exit body and cleanse my entire neighborhood. I would do a mental sweep then drop a tent of white light over my home and expand it outward to push undesirables away. It worked like a charm.

One other method I learned from John Monroe was to manifest a blue orb of light in my hands then project it towards whatever downtrodden entity that happened to be lurking around me.

Today I just ignore things and usually skip over the astral mirror realm altogether. But as you progress you’ll be quarantined to the 4th dimension where some of these simple elementals tend to schluff around.

When you are out of body you lose certain things that pertain to physical bodies. Anger and lust and jealousies and these things that are part of our animal nature don’t exist in the light body. So the intent to elicit revenge on beings will likely be lost upon exiting the body.

In the same breath, if your intention for astral projection is to spy on hot naked chicks then you’ll either be prevented from having an astral projection or you’ll lose that desire as soon as you’re out of body.

That’s been my experience anyway. I dated a girl who also tried to astral project. After many attempts to see her or meet up with her in that realm I was only able to do so twice and she was just floating unconscious above her sleeping body. I did however manage to influence one of her dreams though.
