I don't want to contribute to what could easily be something akin to mass hysteria or a "contagious" form of paranoia (this is a website dedicated to unusual phenomena, with a large share of it being committed to conspiracy theories, so one should probably take that into consideration when interpreting the implications of so many members reporting similar experiences, feelings, and sensations of anxiety, dread, etc.) however this thread reminded me enough of how I've felt intermittently lately to post anyway.
About two weeks ago, I too began seeing odd flashes of light and patterns. In my case, I was told first that I had an ocular migraine, and then that I
had anterior vitreous detachment and was treated with prednisone for inflammation, but was then told I had neither and it resolved shortly thereafter.
In addition, I have had a powerful impulse to go somewhere quiet, more rural or natural in setting, and get away from the city. It started with a
powerful need to see the stars which overcame me one early morning, and grew to such an extent that I finally broke down and reserved three nights
alone at a camp site on Angel Island for a couple of months from now. I fully intend to go. I have an overwhelming urge to leave the city and be
somewhere quiet and secluded for some reason. I've never felt that before.
I haven't had an inordinate need for sleep, however normally I do, particularly in summer, as I am very photosensitive. I usually need tons of sleep,
and the more sun I get the more I seem to require. I could sleep all night, yet still sleep for 12 hours simply because it's particularly bright one
day. Yet lately I can't seem to sleep well at all, and I appear to be full of energy and tension. In my case, it's taken the positive form of
motivation and additional physical activity, however it is still there and appears to be increasing. Of course, I could simply be unused to getting in
shape, in which case this is a good thing lol.
