I clicked on this post because this is happening to me also and it scares the **** out of me. I feel like I am missing my entire life! I was still waiting for Christmas to come, and its been over for weeks! The other day I accidentally told my husband, "Aaron was over there, you know how everyone loves his jokes". Aaron is my deceased brother, now why would that come out of my mouth? For me, I believe my substance abuse problems are totally to blame. I hope you can find out something my friend, and just keep hanging on. Remember the Uncle on "Its a wonderful Life!", who had strings attatched to his fingers so he could remember things? It seems he had something like what you are describing, although it never mentioned what it was except that he was "Absent-minded". Update us with what you find out and good luck.
