Not sure if this is the right forum for this.

I've noticed that when I get to a point where I can actually see an image in my head when my eyes are closed like if i was watching a video on a screen, I start feeling sick. There's a burning sensation around my solar plexus, I feel nauseous, my throat starts getting all itchy, and this may be a coincidence but today I am feeling some heart burn. My initial thought is that it might have something to do with the chakras.

Does anyone know what is going on here? It's already happened a few times and the images aren't even anything in particular. For example, today I was in some building running through closed doors. Before that it was just me looking at something for like 2 seconds. Back when this started (I didn't notice any pain then) It was always the same image for like a second. A black and white surface that kind of looked like the surface of the moon or the texture on the ceiling in my room.
