Mental Image Caused By Conversation With My Brother

I see myself from the back crouched down in front of an open box big enough that I could crawl in and curl up comfortably. We (the box has a persona) are superimposed images upon a black screen. I am holding a physical representation of the phrase "Put All Your Thoughts Into This Box" that is grey, straight, as big as my arm. I do as the phrase says, and put these no-longer-abstract words into the box.
