How to remember Krsna when asleep

Devotee: How does the devotee go about practicing this Krsna consciousness
when he’s asleep?
Prabhupada: Yes, Sleep means your gross senses are stopped, but your mind
works. Therefore you dream. So if you practice your mind to be engaged in
Krsna consciousness, in dream also you’ll see that you are preparing
prasadam. “I am going to sell Back to Godhead.” (chuckles) That’s all.
Sometimes some nights when I feel hungry, I dream that I’m eating Krsna
prasadam very sumptuous. (laughing)
Devotee: Oh, haribol! (laughing)
Prabhupada: (laughs) Somebody is supplying me nice parata and I am eating.
(laughs) But, being hungry, oh, my hunger is not satisfied. I’m eating,
eating, till the dream is end. So if you practice, this is the technique.
