Dreams Lost in Deep

Dreams.. are they just imaginary visuals! or just a simple game of a restless mind!
Dreams..that was with us all along in our mothers womb and will be there till our tomb. are they just... Dreams or something more?

Dreams.. i see as visuals what we have seen already.
Dreams.. just dont form from some unknown part of mind or brain.
Are they really what we have seen. i dont have an answer.

if so,did we dreamt when we are inside our mothers womb?

if we dreamt... what did we dreamt about?
