Well I wouldnt say looks. Maybe feel. It would kind of look like a “simple technicolor light” to a physical body in the minds eye, but you’d feel a separate entity with you for sure. I’ve had this happen to me once or twice very intensly while practicing some home brew weird shit. It was kinda overwhelming. No one will ever be able to convice me that I was not interacting with something. It was 1 or 2 sperate, but one thing, and it literally threw a weird ass tiny ball of white string at me and all my cabinets opened up upstairs. I’m a crazy person. Proceed with caution.
