I assume the wiring of my brain is much like everyone else's but then, I assume I don't require medication.In the course of any conversation, there are trigger words or phrases that set off tiny explosions in my head. The din is generally over quickly and I can continue a conversation or at least appear to be listening.
One of the most common examples is when I hear someone say the word "everything". Before they've even finished the word, a very short visual of Sissy Spacek yelling "EVERYTHING" from the film In The Bedroom plays in my head and then things return to normal. I don't even remember the story from the film particularly well but the intensity of that second plays whenever I hear the word.
Sometimes my brain forces a longer diversion and it's a couple of seconds before I can get back to you. If I hear someone say "This is nice" a whole passage from the film Strangers With Candy plays. Jerri Blank is sitting at the dinner table and says This is nice. Family. You got the mommy and the daddy and the brother and the sister and ... this guy.
There are many snippets of songs that play as well depending on what someone's said but they're too numerous to mention.
It's my brain that takes control in these situations no matter how hard I resist so, should you ever see that glazed look in my eyes while talking to me, it's you, not me, you said the wrong thing.
