If the media shows up, those are drawings that my brother drew to show me what happens in his nightmares.
What he has told me is that they only occur when there's zero light in his room. His dreams in general are fairly violent, but his nightmares kind of scare me.

The drawing on the top left corner is a creature who is bleeding all over the place. My brother explained to me that the dark areas (like the eye sockets), is full of blood. He explained to me that that figure appears when he exits his room in the nightmares and goes into the hall. It appears and then dies. He doesn't really fear it at all.

The figure on the bottom right is a robotic squid girl creature. He explained to me that in his nightmare, she always watches him and later on kills him. She would always stare at him with the robotic eye (the left eye) glowing red. When he goes back into his room in the nightmare, she grabs him with her tentacles and rips him from limb to limb and other gruesome stuff. He said that in those nightmares, he's seeing it in third person point of view, so he basically gets a good view of her brutally mauling him with her tentacles, claws, and other parts.

Geez, times like this make me wonder if my parents think that we're screwed mentally.
