I've lived my whole life with them. You must extend yourself out to them. You'll find them if you look hard enough. Then they will start attaching them selfs to you and the nearby space around you. You must first realize that there real. They will notice you: and drawn by the prospect of some easy pickings come to you. Not all are bad: mostly just neutral like chipmunks scurrying about from another realm. Demons are another thing. Then will give you a free ride if you want. The swap is not usually worth it. They are dangerous and daring. Like kids playing with hornets nests. They always get you back for fooling around.
I used to hang out with my dead grandfathers a lot, and had a guardian angel. But then I started taking anti-psychotics and they went away.
No, I believe in them, but the meds stopped my ability to see or interact with them.
Some... what did you want to know about them?
