Inception Dream Time

inception_dream_time.py

# `dream_time` returns the amount of dream time elapsed in a dream at `level_depth`
# under a sedative factor of `sedative_factor` while sleeping for `base_time` amount
# of time. The units of `base_time` are seconds, and the returned dream time is also
# in seconds, which can be converted as desired.
#
# Tested with the dream time calculations in Inception (the movie).
# e.g. the sedative made by Yusuf apparently has a factor of 20.
