Dream within a dream

Dreams
and the science of it,
don't have any set of
established rules.
One cannot say so easily
what dreams can bring
at times
and it is certainly always not
about
what one thinks all the time.
It brings unknown matters
as also, matters that are not
at all close to us.
I often wonder if dreams
are also some kind of a
communication, like someone
is trying to say something,
trying to get in touch
with me,
or whether someone is
saying goodbye.
But what I don't like about
dream is, when it
brings at times, some
truths that I fear and
some truths that
are lies.
And strange enough,
in most of them,
you always come as
someone, who I always
wanted you to be,
A dream within a dream!
