I was working ourside yesterday in Memphis but consumed water and had lunch. Later that evening while watching TV in bed suddenly i became very dizzy and the picture on the TV began to distort and twist. At this point I lost touch with reality and the person with me said i had a vacant look in my eyes and began making strange and erratic breathing sounds. This lasted 15-25 seconds. When i regained reality i was confused and found myself sweating profusely, clammy skin but orherwise okay. It scared my partner and me too. I am a 70 year old male with no other health issues. I just had a complete physical and was given a clean bill of health. I have experienced one or two dizziness episodes in rhe last year but those subsided quickly and no orher symptoms presented. Any suggestions would be helpful
