my sisters brother in law died. The evening of the funeral his widow was giving the youngest a bath. The toddler stared off over her head, and said “bye bye, Daddy! Bye bye”. Thats pretty weird stuff.
One of my cats does something like that a lot. He’ll jerk his head in one direction, stick his neck out, bug out his eyes, and glare at ... nothing. It creeps me out and I have to physically turn his head to make him stop. (Or maybe he’s just gaslighting me for fun.)
