i'm sorry you couln'dt enjoy your trip to disney. i've never been there, but it's a dream of mine, taking the kids there.
anyway, has anything in your meds changed? I felt like that, the surreal feeling, after they doubled my lithium. i had to go bcak to my old dose.
i can relate to certain smells/pictures/sounds/whatever triggering memories, good and bad. i had a bad childhood, but i have this picture in my bedroom, and i know i've seen it before, but i don't remember where, but it gives me this sense of security, safety, happiness. for years i've been trying to figure out where i have seen tha tpicture, where that connection is. no success so far.
i wish i could be of any more help.
