A Missouri man visiting his son's home in San Antonio, TX, reports hearing a pinging sound outside his bedroom window and then seeing three alien beings inside, according to April 18, 2011, testimony from the Mutual UFO Network (MUFON) witness reporting database.

The witness was reading in bed at 3:25 a.m. on February 19, 2011, when he first heard a "ping" sound.

When the sound seemed to come close to the bedroom window, the witness sat up in bed.

"That really worried me and I wondered how this strobbing sound could get right up next to the house since there is a wood privacy fence 6 feet high next to the window that prevents anyone from entering the back yard," the witness stated. "When I sat up I was glad the blinds were shut and suddenly my vision was blurred by some kind of a vibrational wave that shot down into the room from the ceiling area, travelled through my body, through the bed and floor. There was no sound with it but felt like the vibrations that would come off of a loud amplifier."

The witness then felt "vibrations" - not sound, and began thinking repeatedly in his mind, "Don't come in."

Then a sense of normalcy overcame the witness, who returned to the bed to read. But shortly, he saw two small "grey" aliens in the bedroom doorway, and a taller being standing in the doorway of another bedroom.
