DH and I both do this. We INSIST we've said out loud what we were thinking, but the other never heard a thing. Happens a lot with plans on the calendar, too... "You've got something going on this weekend? I didn't know that." "I told you, AND it's on the calendar." Or... "Did you pick up the milk on your way home?" "What milk?"
When I was younger, thinking an answer would often feel the same as saying it. Nowadays I have to check whether my mouth and throat also feel like I have said it.
So this brings up a question
I've been meaning to ask:
What is the experience like when you "talk" to yourself?
I have several layers of "talking" to myself...
...there's the one where I talk out loud to myself (and get funny looks from people).
...there's the one where I feel like I'm not really talking unless my throat and the back of my tongue are moving, even though I'm not moving my lips or making any sound (this is what makes my throat so tight and sore, but I can't make myself stop...I've tried...AND this undermines your check of whether it
feels like you've said it...BUT it works really well when I'm writing something because it helps me get the grammar and spelling correct without significant errors because I see the sentence structure as I "say" the words and just type what I'm saying "out loud" in my head).
...there's the one where I manage to think in words in my head with no muscle movement (and that's when my thoughts tend to be moving so fast I just can't keep up and I get that flighty feeling).
...there's the layer where I think in pictures in my head instead of in words
I can actually have conversations between the different layers, like there's the one speaking in my throat that converses with the pictures in my head. This sounds really crazy, lol...just wondering if anyone else has different layers of "thinking" like this...
Hoping this isn't too OT from the OP. (and on that note...does anyone else "translate" acronyms in your head when you're reading what people write, or do you just "say" the letters?)
