Yes, I've been "zapped". Don't know if it was infrasound or not. All I know is that one minute I was knocking or whistling with something in the woods late at night and the next minute, I was filled with terror and locked myself in my minivan crying on the floor. A few minutes later, it was like a switch turned off, I felt completely fine, and I opened the door and continued knocking or whistling.
(This happened on one of two nights, same place, same time at night and I no longer remember which is which, in 2012).
