A very good blog post on Messages From the Unseelie Side on the energies of beings; Interesting Times and Safety.
Don’t play around with these things. Aliens, ET, elementals, astral beings, fae, etc. — some are “good” and some aren’t. And as the writer comments:
Contrary to the more ‘white light’ line of thought making friends with these beings or trying to empathize with their situation will not help you. These are not beings who just need a hug and a cookie to sooth them into standing down. No. You can’t feed a cat a vegan diet and expect it to survive and you can’t ‘friendship’ a night mare into feeding off of anything except terror. All things are true to their own nature and the nature of these beings is to feed on and encourage human suffering and pain – and death. In this situation you need to understand what and who you are dealing with and why they are the way they are. And accept that some beings in wider reality are hostile to humans by nature or adapted to feeding on painful emotions or death. -The Unseelie Side
