When I was younger I would see Faeries a lot, especially if I'd gotten sick. My mother would tell me that I would brag about the games they'd play to keep me happy and entertained, and she'd also say I'd play with them in the backyard. Unfortunately,I cannot see them as clearly as I had back then.
I'm not sure if this was very spiritual, but I do know a very kind, loving angel who's name I never learned would visit me every night to brush my hair and tell me stories or words of positive affirmations. This was back when I was going through some very rough times in my life as a child, so I think the angel came to me in order to provide the love I needed at that age. I'd call it a dream, but I still distinctly remember what she and the room she took me to looked like, and I also remember this visit happened periodically for quite some time.
Aside from that and occasional clairaudient experiences, I can't seem to think of any more spiritual beings worth mentioning.
Have a blessed day.
