I dont know whats wrong either, but so far i do know that I get brain fog where the brain kindof stops thinking correctly and dazes a little. (Something about an area of the brain not getting the oxygen it needs-but its not severe enough to cause damage?? Idk. I have done enough reasearch to understand it fully.) For me (yes, its different for everybody) it causes; -memory loss/lapse -confusion - repeating actions or words -misplacment of things -difficulty speaking/wording. Usually ends with me making a noise to ease the awkardness (it dosent work but hey, i tried.) -blank space ((like time skips almost)) -brain dosent know where to focus. -i see messages but i cant respond becase i dont know how to word/read or my brain wont proccess it -i will read words in the wrong order (( for example, today instead of "its okay to not be okay" i read "its not okay to be okay.")) -i will send a message that makes sense to me but has so many spelling mistakes you cant understand it. -i type a message but dont send it -i cant think or get my brain to think Alot of people think its dissocating, and while both have similar symptoms, these two tend to feel different to me. Dissocating (for me) is more of "I'm leaving the body" Brain fog is more of "everything in my brain is leaving me" Plus i tend to get brain fog more so then dissocating. If you experience these but dont know why or just started thinking "maybe i experience brain fog," go see a doctor. It could be just brain fog but brain fog is usually associated with an illness. Plus, many illnesses/conditions cause these symtpoms (that arent brain fog) and its important to adress the cause. I cannot stress this enough. For me its completely normal and might even happen on a regular basis, but if it gets worse i talk to the doctor. You should do the same. ((Good luck if you have doctors that aren"t listening or just suck, But you still need to find the cause if you can.))
