This started this summer, around the same time I met my boyfriend. They all wear navy blue color clothes, although the first one I saw was wearing black, and dress casual. All of them have been men, with the exception of one woman (who was also wearing navy blue). They seem to watch me from a distance and most often these encounters happen in public. Their facial expressions are blank, so I don't think they mean any harm. I usually ignore them and their existence, I'm not really scared. I don't know if the colors mean anything but I would like to know if it holds any meaning. I once prayed to Archangel Michael and they went away for a month. I have looked a bit into it and learned that Michael takes them away, but that the spirits have free will so they may comeback. I don't want to see them, if anyone has had any similar experience please give advice or information on ghost and why they're watching me.
This is extra so you can ignore the rest below its meaningless.
