Do dreams have any link to our lives? Is there any cryptic meaning to them? For example, dreams about flying may have some spiritual meaning. What does everyone think?

(I know this isn't very clear, but I don't know how else to put it! )

life is infact a dream.

everything in life is a lie if you remove the letter f (corresponding to fact)

whatever you fail to do in your life is reflected in your dream.

in my view the best gift given to a human is the ability to dream.
