Today I learned that if you wake up from a dream in which you drank down 3 full glasses of water and 3 bottles of water and were looking for another cup of water to guzzle when you awoke, chances are high that when you wake up you will discover that you feel thirsty.
And it is likely you will get out of bed and stumble sleepily into the kitchen and quickly drink one and a half glasses of water and half a glass of lemonade. And then go back to bed and turn off the light.
Turn on the light again after 2 minutes. Stumble back into the kitchen and drink down another half a cup of really cold ice water. Then post about the experience on Facebook. And calculate that in the past 20 minutes you have drank a total of 8 and a half glasses of liquids, real and imaginary. You then make a mental note to yourself that it isn’t as difficult as you had thought to drink 8 glasses of water a day, as everyone seems to recommend — although admittedly 6 of your glasses of water were drunk during a dream and shouldn’t really count.
You will then get back in bed and turn out the light.
And still feel thirsty.
