Anyone else experience that? For me it's caused mostly by feelings that there are malicious presences. Although I never actually see them, it feels like they might appear at any moment. I have to constantly keep an eye on the bedroom door or else it feels like they get closer and closer. It seems to happen mostly during mixed and depressive episodes, although in this case it started about a week before the actual mood changes. I've never had psychosis, but I sometimes worry that these sorts of things could be prodromal symptoms.
