I sometimes feel like nothing is real not me or anyone or anything around me and I have this feeling that I can only explain as unbelievable surprise during this whole time. it used to last a few minutes now it has gotten worse and can last to an hour or so. i can't find the trigger for it it just happens out of the blue. i went to a therapist and he said he had no idea. does any one else get this? i don't think its dangerous, at least it hasn't caused anything bad ever since i can remember having it ,i just want to know what it could be.
