I had a different experience. For me, it felt like I was inside an empty UFO, or inside an empty room inside a space station floating somewhere in space. I felt like I was in a 2001: A Space Odyssey. That was when it emitted white light.
Then it turned red. A dark room, a horror movie. The room felt evil. The guy in the striped shirt looked suddenly
similar to Freddy Kruger. The blonde girl, on the other side of the room suddenly looked like Carrie. My mood was fear.
Then it turned blue - underwater, drowning, panic.
Then it changed into the lighter, less severe colours. I felt calm again. That thing was like a mood generator or a teleporter.
