This theory proposes that we can understand dreaming by applying the same cognitive concepts we use in studying the wake mind.Dreams are subconcious cognitive processing which involves information processing and memory.Thinking during dreams is similar to thinking in waking life. No special meaning to dreaming - simply dramatizations of general life concerns (ex)Defalt network - a collection of neurons that are active during mind wandering in the day when not focused on a task; dreams emerge from the activity of this network

Why do we dream?

This theory states that dreaming occurs when the cerebral cortex synthesises neural signals generated from activity in the lower part of the brain.Dreams result from a brain's attempt to find logic in random brain acitivity (random neural firing) that occurs during sleepWhile awake- concious experience is droven by external stimuliWhile asleep- concious experience is driven by internally generated stimuli that have no apparent behavioral consequence. This activity commonly comes from neural activity in the brain stem. Stages of sleep cause different levels of neurotransmitters to raise and lower through stages of sleep affecting dream activity as well. Damage to a brain stem does not stop dreaming in many cases suggesting that the brain stem is not the only source of activity leading to dreams.

Activation-Synthesis Theory

Many have the typical thought that dreams and nightmares symbolize unconcious wishes and that analysis could uncover hidden desires. Sigmund Freud came up with manifest content & latent content Manifest Content- the dream's surface content, which contains dream symbols that disguise the dream's true meaning Latent Content- the dream's hidden content or its unconscious, true meaning
