Question

Quizplus · Accepted Answer

Psychoactive drugs are those that alter our mental processes and consciousness.

Theory 1: Freud's Psychoanalytic Theory - Freud believed that dreams are a reflection of our unconscious desires and emotions. Dreams allow us to safely express and process our repressed or unacceptable feelings. For example, dreaming about being chased may represent a fear of confrontation or a desire to escape from a stressful situation.
Research: There is limited empirical evidence to support Freud's theory. Critics argue that dreams can also be influenced by external stimuli and not just internal desires.

Theory 2: The Activation-Synthesis Theory - This theory suggests that dreams are random neural activity that occurs during REM sleep. The brain then tries to make sense of this activity by synthesizing it into a coherent story. Essentially, the brain is trying to interpret the seemingly random signals it is receiving.
Research: Studies have found that certain areas of the brain are more active during REM sleep, when most dreaming occurs. This supports the idea that our brains are processing information and creating new patterns during this time.

Theory 3: The Problem-Solving Theory - This theory proposes that dreams are a way for us to problem-solve and work through issues that we may be facing in our waking lives. Dreams allow us to think creatively and unconventionally, without the limitations of our waking logic and reasoning.
Research: Research has found that people who are trying to solve complex problems or make difficult decisions tend to have more vivid and memorable dreams related to their issues. This suggests that there may be some truth to the problem-solving theory.
