My cat has done this 2 or 3 times in a row now and I'd love any insight as to why she does it. She's in a deep sleep then wakes herself up with a slight meow sound (almost like a slight cry but not too much), then she looks at me surprised, then comes to sit on my lap to sleep. It's really cute but I can't help but wonder why she's been doing this. Is it a bad dream and she just needs reassurance? She is a very healthy cat and doesn't have any problems as far as I know. Any insight is appreciated, thanks!
