I haven't personally had that symptom, but I want to understand exactly what you are experiencing so we can see if others can help.
Does it only happen outside?
Is it your perception of your surroundings that are different or changed?
Do things just look or feel different than they are normally?
I do remember a post like this many months ago. Not sure if it was you or another member, but I will search for it in a bit.
When you didn't have this symptom, could it have been from a medicine or herbal you were on and it was helping with this? If you keep a journal you may be able to check on that.
Is it Ok to ask what your treatment currently is?
Hang in there and I hopefully others will be along soon to chime in also.
Take care and I'm sorry your having this symptom, Jo
