Needle in arm

In a dream this morning, I am lying down when I notice a spot of blood on my upper right arm. I then see the end of a needle, tapped by a small bulb, sticking out of my arm. I pull it out. It’s about 6 inches long and the bottom four inches have a thin coating of blood, like the oil on the dipstick in a car. I wake up.

The location of the needle was about the same place on the arm that I have received vaccinations. Perhaps the blood on the needle is a measure of my resistance to some metaphorical virus. Somebody wishes me ill.
