It doesn't look like right censored data to me, unless the time variable
were "time to full orientation"; you labeled it "time to awake" which
appears to be something different.
However, to answer your coxme question the random effect would be
(1| MRN/COURSE)
which stands for a random intercept term for each course, and one for
each mrn within course. This is the same notation as lmer.
