mmm..the sound for me is more when I'm anxious or in a mixed state too. I've caused a lot of arguements over noise levels in the hhouse, even when they might be at reasonable levels for other people! I actually stomped upstairs my mum was having when I was still living with my parents - someone was banging away on the piano - I yelled at them all to stop that racket. I was so angry. It was awful. So dreadful for everyone to witness too.
The smell thing...I wonder if I should tell my psych about that one. It is very disturbing for me.
