Well I have had abnormal patterns on my EEG in the past during the photosensitive part of the test although I have had a couple of 'normal' ones since then and flashing or flickering lights have always bothered me. Today however I was teaching a kindergarten class and the kids had rotating groups. One of the groups were on the computers which normally do not bother me but this obviously had a problem because it was flickering real bad. Well, at least it seemed it to me but the kids did not seem to notice or be bothered. As soon as I walked into the room and up to the computer I just had this weird feeling. I can't even explain it. I think I felt a little light headed and just strange (does that even make sense) in my head. I felt better once I walked away from it.
