So you're saying you palpably felt when you woke up like you had just lived for days? You had experienced every minute of those days? Like Picard in the flute episode...what was it called again?
Or are you saying days passed by? Because days can pass, but the moments within the dream in which you're "doing something" most likely did not add up to days. In that case, it would be "doing something for two minutes, then it's the afternoon, and you do something for five minutes, then it's the next morning and you do something for three minutes, and it's a day later." That's not actually having days experienced in your dream, just days pass by.
