Just follow the steps:
Try to remember the whole dream - Like places you went, the items, the color. Each detail of the dream matters.Try to figure what where you doing, who else appeared in your dream, what was the interaction between you and other people in your dream, the animals that appeared what they were doing ( dog for instance how the dog appeared in your dream was he : barking, sleeping , sitting in next to you, chasing you etc. ).
Write them down- put these things in a paper and try to puzzle them. Try to figure out what where you doing and what was the relation with others and in what kind of envoriment were you.Is there any message from the dream or it is a random one?
Use dream dictionary - You can find lots of them on the internet. But if in dream dictionary is an explanation for an item that doesn't mean that counts. Try to analyze the whole situation in a long term. See what happens every time you see a bear in a dream for instance. If something good is going to happen then you remember for next time.
Learn general meanings of dreams- Your daily activities and your emotions has a lot to do with what is your state of mind and still ignore that.That's why in your dream will appear your fears,hopes, weak thoughts etc. That's you it is good to know the general meanings like what does it mean when you dream chasing, getting naked,flying etc.
Differ prophetic dreams from the ordinary ones - the prophetic dreams are a really good source of warning you for something bad or good. Try to remember the words that you hear and other things that you saw.
