I'm not sure if this was indras net or another net or what, but last night, I was asleep but partially awake and this picture came up. It was a net of circles and triangles. The triangles were connected to each other and the circles were free floating in between the triangles. It was a 2d picture and looked electric. Then all of a sudden the picture became like a 3d and the circles became tunnels. I don't remember what the triangles looked like but I do remember being able to travel into the tunnel and then everything went black, so idk what happened after that part.
