I've tried to pinpoint what causes it and I can't because these issues have occurred in many different locations. I lived with my boyfriend first and then when I moved in with my grandparents, the symptoms persisted. I'm dumb founded as to what this could be. I'm wondering if I could've possibly transferred mold spores or something when I moved in with my grandparents. Also, I have 2 dogs who both act strange at night as well. My dog will walk into a room and just stare around like he's confused or has no idea where he is. I know I probably sound super paranoid, but I just feel like my gut is telling me that somethings not right.
