I'm not sure if I can explain this so that it makes sense, but here goes...
Sometimes I can 'hear' myself thinking in the voice of one of my male friends. Not him in my head, it's my thoughts and everything, but instead of it being in my voice it's his. The only logical reason I can think would be that he's the person that I've known the longest who's my age and male, and he's pretty similar to me in terms looks and personality, so I'm transposing a voice that is more comfortable in terms of who I am mentally onto my thoughts rather than just having the voice that my body produces. Either that or I'm screwed in the head (I don't understand how thinking works for other people, I thought it was unnatural to think in words when I was a kid and never really worked the concept of thinking out since.)
Is that possible/does anyone else find that?
