Romeo, I think your answer is somewhere in between. I don't think anything is attached to you, nor do I think that it is a coincidence that you are seeing all these things. You are a beacon. A shining light in the dark. They are attracted to you because they feel you are a sensitive. Think about dragging a magnet through a pile of iron filaments. As long as you are in an area where there's a spirit, they are attracted to you, but not really attached. I mean, you could investigate, but I've never figured out what good that really does. If you have a good enough contact with them, you might want to try to ask if they need any help with crossing over. If no, then just leave them be. They seem pretty harmless.
