There are quite a few things this could be. My best guess would be paranoia or a intensified mind, causing you to see things that aren't there. Trust the fact that some can seem far more realistic than they actually are.

Child Creativity is also an answer. Children tend to see and talk about stuff strange to Adults. Perhaps this is a case of that.
