Being raised from bed, we hear, not at home (4)
I believe the answer is:
away
'not at home' is the definition.
(I've seen this in another clue)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for away that I've seen before include "On vacation" , "Playing at the opponents' ground" , "At a distance, from home say" , "Distant or having left" , "Missing" .)
