What Was That??

I live alone. I sleep alone. Not even a pet. Back when I had Sadie the Pug, she slept on my bed, but nothing since. 

So I'm sound asleep, and I feel something caress itself across my bare arm lying on top of the covers.  I tried to grab at it with my other hand, because it woke me with quite a start.  But I grabbed nothing.

I laid still and quiet, listening hard to see if I could hear anything else.  But nothing.

What was that???       Totally WEIRD!

As an added thought, I checked Google and AI tells me:  "Feeling something brush your arm while sleeping is often a normal phenomenon called a hypnopompic or hypnagogic hallucination, which occurs when transitioning between sleep and wakefulness."

(I was a child of the 70s,  hallucinations were part of the convo related to drugs!)
