That would imply that people in sensory deprivation tanks would dream.
I don't think they do though they experience sensory illusions.
Of course the interesting question is why do we sleep. When you're
asleep you're not actually deprived of sensory perception. Most people
will awake instantly if you whisper their name. And dreaming only takes
place during part of sleep. I suspect it has something to do with
condensing and encoding the days experiences into long-term memory.

Why do we dream? I think it is because the brain is a dreaming machine.
Waking life is merely a dream kept roughly in sync with reality
through clues passed in from the senses.

I have found a nice paper
Jan Westerhoff, What it Means to Live in a Virtual World Generated
by Our Brain, Erkenntnis (2016) 81:507–528
The author considers the logical consequences from the theory that
the brain generates a virtual world. Below is how Richard Dawkins
describes the theory in his book Unweaving the Rainbow
"We move through a virtual world of our own brains’ making. Our
constructed models of rocks and of trees are a part of the
environment in which we animals live, no less than the real rocks
and trees that they represent."
"There is an easy way to demonstrate that the brain works as a
sophisticated virtual reality computer. First, look about you by
moving your eyes. As you swivel your eyes, the images on your
retinas move as if you were in an earthquake. But you don’t see an
earthquake. To you, the scene seems as steady as a rock. I am
leading up, of course, to saying that the virtual model in your
brain is constructed to remain steady."
Other proponents of the theory are Thomas Metzinger and Steven Lehar.
Westerhoff offers three accounts for such a theory: strong, weak
and irrealism. They differ from each other on the account of an
external world.
The strong account implies a structural correspondence between the
virtual and external world. The week account just says that the
external world exists but one can add almost nothing to this end.
Irrealism on the other hand states the the external world is a
part of the virtual world. I guess that Bruno's theory is close to
irrealism.
