Do you ever have repititive/deja vu dreams?

Tweet

A few years ago I kept having those dreams where I would be falling and I'd be falling really long and then when I crashed to the solid surface I would twitch and wake up right then. I don't know if those dreams had any meaning, but it was very strange as I talked to a friend then later and she told me she had same dreams, so do you think we could be going some same strange stage or something that we kept having those dreams? that was in primary school ar around 8th grade and now sometimes my dreams repeat too, but not like before, only some parts like in dreams I will know I'm dreaming and it will be like deja vu, some particular subject or something in dreams usually triggers it and sometimes then I have this 'deja vu' feeling in 'real life' I'm doind something or am out with friend and it hits me, but usually I can't put my finger on it what is it, just this strange feeling. So what do you think? Do you believe dreams have a higher meaning and if so what it could be? do you ever dream like that/repetitive?
