Hi Mr Al
Apparently something as innocent as a Jumping Spider pictured here:

Lots here where I live.......
When my whole face was sore and I had bumps coming out all over my face ... and constant headaches.. I finally consulted a Doctor.
He took one look at me and said you have been bitten by a Black Jumping spider( many species and types). Incredulously he analyzed this way too quickly for me. Amazed I asked how he knew???
Doctor says " My Wife got bitten by one and she ended up in Hospital".
Enough said. As it is I am petrified of Spiders.....never mind one sitting on my face when I am sleeping and biting me
Anyway Mr Al, you wanted to know. Now you have the answer. Sweet dreams
Evil tvech here LOL
