There are indications that yoga (meditation) was practised (or at least prescribed) between the two phases of sleep, at midnight, in Pāñcarātra texts – Marion Rastelli has written a bit on this in her paper "Yoga in the Daily Routine of the Pāñcarātrins" - I can send you a pdf of this paper if you like,

Best wishes,

Dear Colleagues

this led me to wonder whether anyone has run across any indications in Skt (or Tamil) literature of this so-called biphasic sleep.
