I have seen more mind boggling stuff with my own eyes first hand, so yeah I can think its possibly real, because of that fact. My own observations includes a large craft hovering above a house, the craft itself being about the size of the house, and it turned on several lights in many colors before it started to hover away without any sounds.

Few minutes after a couple black helicopters came flying around, which very VERY noisy as I noticed, in comparison to the larger craft that was completely silent.

And that is not even my most interesting or strange observation.
