I can relate to this, I think people on the street who walk towards me then turn back and walk in the opposite direction are doing it to send me a secret message or threat. It could just be that they have forgotten something at home and have turned back., It seems to happen all the time though.

I also think that cars deliberately slow down when they approach me -stare at me then drive off.

I think people break into my apartment to move things around in order to wear me down mentally.
