Does anyone else’s cavi sleep with their eyes open??

my girl nearly gave me a heart attack yesterday because i looked up from folding laundry and she was laying on the couch with her eyes wide open and wouldn’t react to any movement or noise. after i finally walked over the to check on her, she rolled over onto her back looking for belly scratches. she doesn’t sleep like that often, but it scares the crap out of me when she does! anyone else have a cavi with weird sleeping habits?
