If someone wakes me up by talking to me, I won't have much of a clue what they're saying. I can hear them, and I might mindlessly repeat something they say, but I won't consciously be paying much attention and will forget the conversation and whatever I said during it soon after. I'll remember that the conversation happened, but I won't remember what was said. One time when this happened, my heart was beating so fast I thought it was going to literally burst. (I realize that part at least isn't normal and is something I should get checked out if it happens again)
This wasn't always happening. It started around last year. I've also been having unpleasant feelings in general when waking up lately that are hard to put into words, but they're mostly in my head and sometimes my chest.
