i spent an entire day in a dream once and woke up only to find it had only lasted the night... i still remember distinct parts of what i did that day in the dream, i did a full shift at my work and conversed with people, came home, hung out with some freinds, went to target and bought a cd, etc... i remember it all to the point i went to bed for the night in the dream... i went to bed on a tuesday night and woke up and thought it was thursday because i thought i had just spent my wednesday in real life, it was all so very realistic and detailed, very disorienting upon awakening
