On being back from the forgotten land of rdreams

Woke up with the vivid sensation of the dream, the colours, the words exchanged with the denizens of that land. Then it was all gone, all of it. Couldn't recall anything, not the plot or the characters I'd met ... not even the sensations arising from it, just the general impression of vividness and meaning. We're allowed to visit strange lands in our dreams, with the condition that we do not remember them on waking up.
