Welcome to my head

One of the interesting things about being me is that simply by reading, hearing, or smelling something that I last read/heard/smelled during a time of an intense emotional event, I can recall the identical feelings to that event. I don't know if this happens to anyone else, but no one's ever told me about it, so I'm stuck thinking I'm the only one. (Granted, this is the opposite of what I used to think which was, if no one said anything about it, it must be true for everyone. But still...) This happens to me frequently, almost daily. Yesterday, I re-read my Australian travelogue, but only the day where I visited the Reef. (That would be Wednesday, 13 November 2002, for those of you keeping score at home.) Just in reading it and looking at the pictures, I can remember exactly the agenda for the day, what the boat looked like, the water, the fish, the anticipation and energy. I feel it deep inside me. The same depth of feeling happens for other things - when I see Erin, when I see a sign in clinic for the "shot/procedure box", my anxiety spikes, just like before. Despite the fact I'm a blood donor now. (Yes, really, I'm a blood donor.) It's weird, but it's exciting, though, and usually I think, "Wow. Hey. What was that?! That was cool. I wonder if I can do that again!" and try to set it off. So does that mean, since I'm trying to get it to repeat, that I'm not feeling anxiety, but something else? Or that I'm just nuts? Never works then, however. Only the first time each day. But repeatedly, cyclically.
