Gremlins or Goblins or Aliens???

This guy took this pic and his grand kid or grand something got it and posted it on http://www.ghoststudy.com/. The question is what are those things??? aliens?gremlins? goblins? I do not know where he took this but it may be an alien maybe escaped or perhaps gremlins, since they do look a little angry/happy/evil. It is hard to tell what gremlins are feeling. I think that it is very unlikely that they are goblins for three reasons: 1. goblins wear more clothes 2. goblins are often, if ever in a picture, hard to see 3. goblins have less hair. The one in the window seems too be carrying a black box or weapon (alien death ray?). It may be something like this box that those blond long- haired aliens used to kill a bigfoot (helpers of human-like aliens) (post a comment if you want to say what YOU think)
