I saw two earlier this year, sitting (or appearing to) on a patio chair. It gave me a good sized jolt, but the fear faded fast. They were conical, dark gray with darker "eye" areas. They did not move an inch and just stared at me. I felt no emotion or communication from them. Carlos Castaneda called them "inorganic beings" and said they wanted to use our energy in their world.. I have not seen them since.
