Dreams are everything. They could be psychic, they could be past lives, alternate lives, they could be your subconscious and they can be meaningless nonsense. This is why I love them so much because every thing is possible!
When I am recalling a dream, it take them with a grain of salt, and replay them in my head as entertainment. Sometimes when I think about a dream they are really profound and I write those down or record voice notes on my phone. I like voice notes because its easier to be descriptive and then I can play them back later.
I would suggest that when you feel you had a dream that is special and not nonsense to write it down or record it. That way if you have a similar dream again you can keep record and reflect back on it at a later time and see what the similaries/differences are.
