Summary

Consciousness refers to the state of being aware of and able to think, feel, and perceive. It is the ability to be aware of your surroundings and make decisions. It is also what makes us unique as humans.

There are many different types of consciousness, but the two most important ones are waking consciousness and dreaming consciousness. Waking consciousness is when we are awake and aware of our surroundings. Dreaming consciousness is when we are asleep, and our brains are more active. During REM sleep, our brains can be as active as when we are awake.
