i read online that there are multiple creatures in the astral realm that you could encounter such as angels, demons, or even the spirits of loved ones long gone, does anyone have experiences with that?
I know you can. I havent been able to project further than my room yet tho. But I know a few people who have seen all kinds of weird astral parasites and monsters there. Think of the insidious movie with that red and black demon thing lol. Also Im sure they have other human travelers and stuff. Go to reddit and search for the astral projection sub reddit youll see a lot of stories. Sorry I cant help more
Whilst these things are part of the astral what you have to also understand is that our imagination is also part of the astral. Most people encounter self created monsters and demons at first rather than actual or external ones.
The astral plane is malleable to thought our creative process I.e. imagination and visualisation. Expect to see such things and you will.
It is a plane in which the external and yourself can meet but a place which is so subjective that any external influence is first filtered through your subconscious as that is the only language these beings have access to to communicate with you.
