I'm reading 'Dead Air' by Iain Banks at the moment and in it is a bit where one of the characters mentions the end scene in 'Total Recall'. It says that because the end scene is so completely far fetched (ie, the whole of Mars gets a breathable oxygen atmosphere and standard pressure inside a minute and Arnie's eyes pop back in with no harmful effects etc) this suggests that the whole thing was not supposed to be reality but was the unfolding story of the memory implant that he had, which started playing out from the point in which he went into the recall office at the start of the film. I always thought that it was supposed to be actually happening as they said that they hadn't actually put the implant in at the Recall office, but I suppose that could have been at the starting point in which the implanted memory began (if you get my drift). But, when he is choosing which type of female character he wants in the implanted memory they show a picture of exactly the same women who he meets later on Mars which suggests that is is all an implanted memory. But, towards the end of the file arnie says that he dreamed about the girl even before he went to the recall office (shown in the dream sequence at the start). Does anyone have any thoughts / theories on this ?
