Symptoms: The person occasionally appears to have no awareness of people in proximity, not all the time but more often than usual and to a very unusual degree:
Walking accidents, that is walking and crashing into someone. Sitting on someone else, or sitting steeping on a foot etc. Standing in a doorway, while other people blocked from passing wonder what is going on. Or at the supermarket stops with the carriage and steps beside it to look at products, thus completely blocking the alley, and can stand there even when someone comes to a stop and waits and eventually says 'excuse me'. In a crowded place many people can get pushed around because if they stand next to this person (you usually expect a close person to be aware and not hit you step on you or push you) but the person makes movements as if there were no one or if the people were much farther away, so appears to be unusually rude for people that dont know. Other data bit, the person is more likely to get burned from cooking or handling hot objects than what I consider to be average (as a reference, I might touch something too hot while cooking once per 8 years, but this person would accidentally touch something too hot 10 times a year or something.
Is this simple absent-mindedness or below average awareness, or is there a name for this type of condition?
(I can be absent minded myself, but I usually have an auto-pilot mechanism that allows me to avoid obstacles while walking etc)
