My anxiety has really been pretty under control for the past week, until today. Earlier I started feeling like my breathing sounded weird and that made me feel very anxious, that ended up passing and I felt fine. After that I was walking through our house and when I would glance one way I would think I would see something but when I would look again it wasn't anything. It was really weird, I wear glasses, mostly for reading or when I use the computer, and I was not wearing them at the time. Can anxiety cause this? Could I just be tired? My mind immediately thought, I am hallucinating/going crazy/seeing things, and then I panicked. Anyone else experience this before?
