I talk to myself when riding home in the dark at 3 or 4 in the morning. I appreciate the company ...
I used to be Schizophrenic, but we are all ok now.

at least it's not as bad as when my kids were younger, when I'd find myself whistling Postman Pat as I walked along the street....
My Mum was a Primary School Teacher for years, so you will hear her subconsciously humming or singing kid's songs all the time.
Heard her singing 'The Golden Cockerel' the other day there.
I haven't heard that in YEARS!
I have been know to greet cows/sheep as if I'm tired and haven't seen another living soul for a while.
I'll say hello to animals as I pass too. I may even be heard saying
'MOOOO!'
to herd of cows as I clatter on past.
I sometimes sing "ahhhhhhhhh" when going down hill on cobbles, causing my voice to wobble amusingly
I've never done that
....Much.
I also do a great 'Wilmaaaaaaa!' (off of The Flintstones) going under echoey bridges - sounds great.
When cycling though old tunnels and echoey bridges, I make steam engine noises, CHCHCHCH CHCHCHCH CHCHCHCH CHCHCHCH CHCHCHCH CHCHCHCH WOOOOOOOO! WOOOOOOOOOOOOO!! CHCHCHCH!!
It ties in perfectly with my breathing you see!
I imagine I am a Black 5, Jubilee or Duchess*

, but I used to do a great 'A4 Chime' when I was young, complete with the split sound. I haven't tried the 'chime' recently. I can't imagine why.
* - Or if I am diesel then I am a Western, and an electric a class 87
