It probably means you have cats. (I love cats btw)
Probably the closest thing I have ever had to an “encounter” was what I call a physical nightmare.
On a normal night without any foreboding dream leading up to the event I was “attacked”.
It felt as though someone with great weight had thrown a mattress on top on me and jumped on top of it.
By the time I was consciously awake I had rolled off the bed and had a gun in my hand searching the room for the source of the attack. I went through my home one room at a time lead by my .357 expecting to find someone or something again and again, then going back turning on every light checking every closet.
But there was nothing to find. There hadn’t been any kind of event like an earthquake or loud noise.
It was a few nights before I really had a deep sleep, but it was a 1 time thing.
I was never able to put any rhyme or reason to it.
