Yeah it could be.
I know the fear and anxiety from HPPD has made me very obsessive, hypersensitive, and less confident... leading me to be terrified of any thought that is out of the ordinary. So instead of taking a CEV, after image, movement in my visual field, or a trippy thought for just what it is I go into a negative loop filled with anxiety because I`m basically thinking "OMG I must be going crazy!"
