Things are not always as they seem. Like, have you ever looked at a picture of a dog and thought, "Wait, that's just a wall with some stuff on it?" No? Just me? Alright, moving on.

Or what about this perfectly ordinary house? Clearly, it's a portal to another dimension. Check out the dimensions.
And don't even get me started on this completely unremarkable rock. Read the epic tale of Rockzilla.
More things that are hidden in plain sight, or not.
