Rest can come from such hypnotic states (7)

I believe the answer is:

trances

I'm a little stuck... Click here to teach me more about this clue!

'hypnotic states' is the definition.
(I've seen this before)

'rest can come from' is the wordplay.
'rest can' can be anagrammed to 'TRANCES'.
Though, I'm not sure how this is indicated.

'such' is the link.

Can you help me to learn more?

(Other definitions for trances that I've seen before include "Hypnotic states" , "what half-conscious people experience?" , "Recants (anag.)" .)

I've seen this clue in The Globe and Mail.
