So recently ive been seeing things out the corner of my eye like shadows and some time specs or particles i though i was hallucinating, it may sound odd but sometimes i look in the mirror and feel like im looking at someone else?

See doctor: Your symptoms are of concern and you should see a doctor, preferably a psychiatrist for an evaluation. Early intervention, if needed, would be important in dealing with the issue. It is not feasible to provide a meaningful opinion in this forum, without examining you and talking to you. Wish you good health!

Symptoms: Your symptoms may be psychogenic and/or physiologic in origin. Would be advisable to be evaluated by bot an Ophthalmologist and a Psychiatrist.
