Hobson’s Dreaming Protoconsciousness
Dreaming as the Brain’s Virtual Reality Training Ground
J. Allan Hobson proposes that REM sleep is a protoconscious state, a genetically programmed virtual reality in which the brain models a world and a body without external input. Dreaming shows primary consciousness (perception, emotion, a situated self) in nearly pure form, and REM sleep trains and maintains the generative machinery that waking consciousness, with its language, reflection, and volition, is built on.

What consciousness is
Consciousness is the brain’s generated model of a world and a body. Primary consciousness is this model running (as in dreams), and secondary consciousness adds language, metacognition, and voluntary control on top.
Mind and body
Conscious states correspond to positions in a brain-state space defined by activation, input-output gating, and neuromodulation, so each kind of experience maps onto a physiological profile.
Mechanism
The AIM (Activation-Input-Modulation) model: conscious states are fixed by the brain’s activation level, whether processing is driven by external input or internal generation, and the balance between aminergic and cholinergic neuromodulation.
Core claims
- Dream features (vivid imagery, intense emotion, lost self-reflection, disorientation, amnesia) follow from REM’s position in AIM space: cholinergic dominance, aminergic withdrawal, and gated input and output.
- The abundance of REM sleep in fetuses and newborns suggests it develops the circuitry for consciousness before waking experience exists.
- Lucid dreaming, in which secondary consciousness partly returns within a REM-generated world, is a measurable hybrid of waking and dreaming.
- Dreaming reduces the complexity of the brain’s generative model, giving sleep an information-theoretic function.
Criticisms
Reports of dreaming in non-REM sleep weaken the tight mapping of protoconsciousness onto REM. The developmental argument rests on timing (REM is abundant early), not on a demonstrated function, and REM’s early abundance may have other explanations.
Implications
- Survival beyond death: No
- Since consciousness here is a product of brain activation and neuromodulation, nothing in the view survives the brain’s death.
