DON'T OPEN THIS PICTURE,
unless you are really sure that you want to see an image of crowley's "trapezoid" demon-mentor from pre-1905, which later came to be known as "alien from outer space".

You would feel a really bad and nerving presence of something really evil watching you behind your back (don't know about all this smell stuff though). Even when you encounter one of those things "trying" to look into your eyes (it feels like those things don't have eyes) you would immediately recognize that this is it, the demon is before you.
Usually though they tend to lurk in the shadows, because they fear daylight and act through midnight to 3 A.M. (also called "devil's hour" or something like this).

Yes, they look and feel black, probably because they lack the God's Light which is the Knowledge of Truth. As every single one of those entities (like so called "aliens") they fear the God's Name (muslims and jews also claim invoking Elohim or al-alah helps, but i wouldn't trust some sandy goddess). Invoke the Name of Christ and they are gone (at least for some time). They usually feed on evil deeds and thoughts. Expect them visit you very often if you're not a True believer in Jesus Christ.
So: pray to Jesus to save you from them, invoke Jesus name, stop wishing to feel their presence.
