Hmmm. I think I have those types of images going on in my mind throughout the day and when I'm falling asleep, too. Clear, vivid images (often with sounds, usually remembered words or music). I seem to remember details of memories, especially those that involved strong emotion, that most other people don't recall.

For example, I have stark memory of New Year's Eve 1999 in which a friend and I were watching glorious fireworks in the sky. We were holding hands and jumping up and down with the excitement of the night, and she was saying some things to me. A few days ago I brought up that memory to her - a memory that is so clear and meaningful to me - and she seemed vague. I don't think she remembers the moment, at all.

That type of thing occurs with me frequently. I used to think that people were just thoughtless, forgetful, or that they didn't really care. Now I wonder if people who don't have MI simply don't receive the "imprint" that I, a person with bipolar disorder and PTSD, receive. Perhaps their brains are just not as sensitive to stimuli as mine is, so they forget more quickly.
