Houdini had composed a secret code of 10 words that was used to enable one to contact something in a different dimension. A ghost is nothing more than a manifestation that remains in the threshold between one plane and another, lets itself be seen for a brief glance, and then hides. The idea of simultaneity is present and once again it urges us to think of ourselves in synchrony with the environment, its limits and possibilities. The physical connection is always present, at least while the body is performing. Once again, several worlds remain united. Can we escape like Houdini? Or is it just an endless illusion? ⚠️ Attention! You may be facing a simulation.
