I was driving from Massachusetts on Connecticut 189 to Griffin Place in Windsor, CT (CIGNA and other corporations were my destination). I noticed in my left window (I was the driver) the black triangular UFO. When I first say the object, I thought it was a UFO. It remained essentially stationary throughout my encounter of the second type. I felt a calming sensation, sedative effect…as if there were nothing to worry about. I lost sight of the object because I continued to drive down the highway.
