Why is my dog singing 80's glamrock in his sleep?

[Wonk]

Poll question: Why is my dog singing 80's glamrock in his sleep?

He's curled up in the corner having a nap, and he tends to snore (mostly on the inhale), but I swear I just heard him sing a line from the chorus of "Bringin' on the heartbreak" by Def Leppard on one of his exhales, both the lyrics and melody. He has basically two voices, his "bark" voice and his "whine" voice, and he was singing in his "whine" voice in his sleep. He had the melody bang on, and was really close to enunciating "you're bringin' on the heartache" properly as well, though I have no idea how.

Now he's back to just snoring regularly again. He only sang the one line, but that sure was weird to hear. I wish I'd recorded it.

1. Maybe his fillings are picking up radio signals.

:shrug:

2. Because he can't stand it when he's awake?

...or something to that effect.

3. I say "Other" because you didn't have a category that included

drug induced visions.

What the hell have you been smokin' Wonk?

4. I don't agree with your dog's definition of glamrock
