I just wanted to let you know my experiences with those things. Around five years ago, I would see those things everywhere, just standing and watching me. At first, it was just a quick glance at something shadowy moving amongst the palm trees. Then maybe a year later, those things just would appear out of nowhere and would just stare at me. I would look straight at them and they would be unmoving. Later they started moving around; moving from behind one tree to the other. But then one night I woke up in the middle of the night and looked to my door, and there was one just standing in my doorway, watching me. It was horrifying, but I don't think they would hurt me or anyone else for that matter. They just seem to be observing but after I moved, they stopped appearing. Today, when I found out there are more people who have seen them, I feel more comfortable and I feel that I really did see those things.
I am seeing them again; they still just stand there and observe. I am less scared but I have tried calling out to them when nobody is around, and they just walk away. I hope I can find out what they really are. I don't, at all, believe they are demons or angels, and I most certainly don't believe they are aliens or time travelers.
