Things started to become dark. There was some sort of opening in the "screen" so I directed my attention towards it. Suddenly 4 spiders started crawling, one after the other, from that opening in a very mathematical fashion, each of the them aiming for one of the 4 corners of the field of vision. At first I was scared, but I decided to investigate further so I went in.
The moment I went through the opening I understood I had "broken through". I was in hyperspace and there were n-dimensional centipedes all around me. I knew they were n-dimensional because their "legs" were not continuous, but rather I could see parts of the legs, and their movements suggested that the legs go through higher dimensions and "poke through" the 3D space I was familiar with.
I was no longer scared. I decided to ask the aliens if I was okay.
Then, as the aliens focused on different parts of my body, the width and height of my inner screen started to change such that, if they were examining a leg, for example, the width would be short and the height - long, as to fit the leg. It reminded me of a technique Guy Ritchie used in some of his movies.
The aliens told me that there was something in my chest and that I should go for a check up.
Then, very surprisingly, they were like: "Oh, you are seeing this hot girl!" and they gave me thumbs up!
