IMHO of course and my toilet agrees
You say an explanation is in order? OK, I just spent about three minutes waiting for my toilet's tank to refill so that I could walk. It's like that every time when I'm "off".
It is sensory overload and it can come from visual clutter as readily as from auditory. It is so pronounced that I now just lean against the wall non-chalantly and wait. As soon as it stops I can walk almost normally. The doorway presents a similar problem - so many straight lines going in different directions!
Schizophrenics have similar problems separating important stimuli from "chatter".
