Question: why do we dream

Rosie Cane answered on 15 Jun 2017:

When we are asleep, we technically lose consciousness of ourselves and have no control over our bodies, apart from something called our ‘sub-conscious mind’. This keeps on working while we sleep and allows us to dream all night long. The kind of dreams we have normally depends on what kind of day we have had or what we were thinking of before we went to sleep.
