This is caused by a little known effect called collapseonomy. It's when the space between your bodily atoms is reduced as you move towards the auditorium, which - and I have it on good authority - is actually the size of a matchbox. The effects are completely unnoticed at the time. But on leaving the theatre, there is this strange-worldiness feeling you get as your foot hits the pavement outside. Most people put it down to the darkness /gloom inside, a sort of 'suddenly in the outside' again, and it soon passes with no more thought. What actually has happened is the final alignment of your bodily structure to it's natural state.

‘Did you know that Macbeth was a maggoty apple? Not many people know that!’
