I'm going to go against the grain here and say that this short/scene didn't do much for me in my personal opinion. It lacked substance! There was nothing there for me to latch onto.
If I understand it correctly --
A person, walking down the street, sees a light or a UFO. Wakes up and realizes something is wrong. Has a flashback or a vision of some mysterious being. Then he's on the balcony taking a swig of water and sees the light again.
I don't really see a compelling story here. Nothing new for me at least. I didn't even find it beginning to scratch the surface of anything. Just felt too loose.
Does this person have some sort of power now that he was abducted?
If he does was this intentional or just a byproduct of being abducted?
Are the beings hostile? Friendly?
Why is the light coming back at the end? Unfinished business?
What is the passing of time from when he sees the light on the street and on the balcony?
Is this the first time he's being abducted?
So many unanswered questions. Believe me, I'm a fan of ambiguous endings when done correctly. But when the entire story is ambiguous because it doesn't give you anything to grab hold of and follow, then in my opinion, that's a problem.
Just some thoughts.
