suppose you are going to sleep and have a dream
you encounter a magical spirit that looks like a little glowing orb.
it asks: do you want to become a mouse?
and then you wake up from the alarm.
you go to work. do the work and come back, rest, and sleep again.
the same dream repeats several times and eventually you just answer: yes!
you wake up from the alarm and turned it off.
you discover that your hand is covered in white fur.
you touch your face and feel that its shape changed.
