Prompted by the trailer for the new Time Traveller's wife series (I love that book) where he says "time travel is a disability not a super power". It has made me think...
I have epilepsy and after a (tonic clinic) seizure I'm either unsure when/where I am, or convinced I am at another place/time in my life - if that makes sense! For example, last time I was convinced I lived in my old house and my DC would be late for nursery if I didn't get up. Said DC are actually at university now  The feelings are absolutely real though, and very detailed - I "see" my old house in my mind eg the book I am reading on my bedside table, the particular lipstick on my bathroom cabinet and for example, a postcard from a friend. (20 years later I wouldn't have a clue normally when/where my friend had been or what lipstick I was wearing in 2003, so these are genuine memories that are being "thrown up"). It really is like time travel, I'm genuinely in my old house and my DC are really nursery age.
These periods aren't like a dream, or even lucid dreaming, it's different. Sometimes it's frightening, a couple of times I have come round and genuinely not known where I am, or who I live with, I see the bedroom door but have no idea where it leads and what's behind it IYSWIM.
My neurologist has told me about "jamais vu" - the opposite to deja vu, so things that are familiar, appear that they aren't. People can also experience this by saying a word over and over until it's meaningless, or if you stare at your face in the mirror for long enough, it seems unfamiliar.
The most annoying thing is that I actually have a poor working/short term memory due to either the epilepsy or meds, so I can't tell you what I did five minutes ago! I also have big holes in my memories day to day, for example I don't remember big events or things with the DC that they/DH remembers. So it's really strange to go back in time like that to certain things so clearly. Maybe it is as close to time travel as you can get...mentally not physically? Brains are so weird....
Does anyone else have anything similar (it's definitely not like having "normal" dreams even realistic ones) or does anyone just find it interesting to think about?
