If a dog IRL bites you while you’re dreaming do you feel it?
If a dog in a dream bites you in a dream, do you feel that?

Strange question, I know…

in my dreams i only sometimes feel the pain i think is being inflicted on me. for example i dreamed i was shot, it was completely painless!
i dreamed i was giving birth, it was the worst pain ive ever imagined, even compared to RL.
on the other side of the spectrum… i have been awoken by spider bites, so i assume you COULD feel it, depends on how deep a sleeper you are i guess?

Yeah, I expect you would wake up if a RL dog bites you.
A dream dog, it may or may not cause dreamed pain.
