What planes of existence does everyone visit while sleeping according to the Great Wheel cosmology?

When someone is sleeping what planes of existence do they visit according to the Great Wheel cosmology in D&D 5e?

I have not found exact information in the rule books about this. Perhaps there are options (good dreams on one plane, nightmares on the other)?

As far as I remember, in one of the previous editions there was a separate plane you went to while dreaming, but what about for D&D 5e?

Is there a mechanic, for example, describing a transition during sleep, a possible death during sleep, or a transition to another person’s sleep that would shed light on this issue?

Maybe there is information compatible with D&D 5th edition in the books about Planescape (since we are dealing with the Great Wheel)?
