I don’t remember Alex. Might have been a real person. Stream of conscientiousness is a possibility. Astral projection? Not ruling anything out. Its the age of imagination isn’t it?
But what more does a sketch of a dog do here than inflict pain on the anal anatomist? All graphics, all images are just tokens which pull on the strings of memory. It’s only a trigger. The eye presents the image to the brain. The brain sorts thru experience. Ah, yes, here is an image of that mongrel dog that snarled at me once, it says. Suddenly this rough rendering is replaced by the remembrance of a real dog, just as scary, just as menacing. Think of how dreams rework the literal image to convey emotion…fear for instance. This dog would have a pretty nasty bite. Overbite even.
