I saw this question
, but my dog's dreams seem rather unpleasant in comparison.
My 13.5 year old dog thrashes around when she's having what I believe are dreams. Sometimes she seems happy, just moving her back legs a bit. Other times, she thrashes about. She'll kick her back legs around very quickly and sometimes whimper. I've also seen her lift her head off the floor and put it down again during what seems to be a particularly intense dream., and I worry she's going to hurt herself on the hard floor (I doubt it would case serious injury, but possibly a headache). Her eyes are also partially open, so it gives the appearance of her being upset (although, I know this doesn't mean she's necessarily upset).
Basically, she seems unhappy at times while dreaming. I can't tell if my perception is off and she's having a wonderful dream though. Last night, she thrashed around quite a lot and I worried she was having a bad dream, so I woke her up. She seemed to be very deeply asleep because light petting and lifting her front leg didn't wake her. She did eventually wake up and seemed a bit dazed (which reminded me of how I feel when woken up from a bad dream).
I've had her since she was a puppy, so she's never been abused. She tends to be rather anxious though - she hates the sound of thunder for instance.
What does the hive mind think? Do you think she's having bad dreams or good ones? I feel bad waking her up if she's having a happy dream. I know there's not a definitive answer here, but what's your opinion?
