I have epilepsy (nocturnal so usually a seizure just before waking). I have had a previous thread about the oddness of the post ictal period as I don't recognise the present (jamais vu as opposed to deja vu) and am convinced I am in the past when I come round. This isn't like a memory, it's really like time travel in its level of clarity and detail eg the other day I was convinced my DD didn't need to be picked up primary school as she was going to her friend Joanna's house for tea. I did not believe DH when he said DD is actually at university at the other end of the country 
I knew what subject DD had as her last lesson at school that day, what I put in her lunchbox and how her hair was plaited etc. DD doesn't even remember Joanna as it was a short lived friendship and I don't think I would even remember her name under "normal" circumstances. In addition I have had instances where I recall "provable" stuff like car registration plates, postcodes, insurance reference numbers etc from over thirty years ago. I do not have anywhere near that level of memory in "real life" in fact my short term memory is fucked due to seizures/meds and I usually can't remember what I said/did 10 mins ago!
Anyway, recently I have had uncontrolled seizures and a change of meds and have been having extremely lucid post ictal periods but (this sounds ridiculous typing it 
) they are different and I believe it is the future I am "seeing" not the past. Bear with me As this thread is already outing I can't describe the exact scenarios as they concern my DC, but they aren't situations that I already knew about subconsciously or could have been told about and forgotten, these are one off and very unlikely events that couldn't have been predicted eg a week after my seizure, DD meets a brand new friend in a bar who <insert something niche and unexpected here like their father is now a monk, or their aunt is a member of Hearsay> I haven't told my DC about these seizure "visions" so they wouldn't have known this would happen.
I realise I sound a trifle unhinged let me reassure you I am a cynical down to earth person in RL who doesn't believe in any creepy woo bollocks.
My seizures aren't controlled at present and in the last three I have woken up in a room that is very detailed and I absolutely believe it exists and I or one of my DCs will see it in the future and possibly live in a house with it? It isn't a grey standard living room with a feature wall (sorry to people with this room) It has a distinct patterned carpet and white wardrobe and storage with particular handles.
I am actually laughing a bit myself typing this, as it sounds so ridiculous. I suppose I'm posting partly in the hope I can come back to this thread in five years with a photo of said room (imagine!) but also interested in MNers opinions especially non woo type believers like myself (usually). My last thread was interesting as some people had experienced the jamais vu phenomena so maybe someone has also had this? The irony is I would assume they are talking bollocks normally
