I can go to sleep fine but when i wake up in the middle of the night i find it hard to go back to sleep. When i shut my eyes i get flashes that light up my eye lids every so often only mild but enough to notice. I have weird random thoughts, like they just pop in my head for no random reason and don’t make sense without me even trying to think about out. I think sometimes when my head is tying to rest it makes random noises that feel like they are on the outside but probably inside my head like “exploding head syndrome”. These random noises sometimes create random thoughts like last night the noise i heard made me think of someone shooting a RPG because of the explosion. It’s weirdo how it does it. I notice it more when after i wake up and try go back to sleep during the night.I am guessing it’s all just anxiety and stress related. Never have any of these symptoms when i am wake and up and about. Only when trying to rest my head.
