I have been seeing colors around objects and people off and on for the past several months.I haven’t noticed anything different that I may be doing to cause this.Just today I was writting a check and from my hands I saw the color of orangeish yellow almost stain the check. I then took my hand of of the check I was writting ans placed it on my thigh and I saw the same colors.Has this happened to anyone? Why is this happening now? I have also been noticing sparks of blue or bright flashes around me and sometimes lights flicker.What is going on with me??
