Why do we Dream?
We don't dream! Our brain dreams!
Oh AumSum!
One theory suggests that we dream to fulfil our wishes.
It states that we are not able to express all our thoughts consciously, hence some of them find their way via dreams.
Another theory called 'Threat Stimulation' suggests that dreams are basically a defense mechanism.
For example, nightmares put us in threatening situations, thus allowing us to practice our fight or flight response.
Some people also believe that dreams don't really mean anything.
