Dream interpretation is a not uncontroversial topic. The dream interpretation or oneirology tries to interpret the feelings images and actions experienced in the dream. Since there is no agreement on the function of the dream in scientific dream research the interpretation and meaning of dream content is controversial.

Very important for the interpretation of dreams are the dream symbols that is things that you dream about or that appear in one or recurrent dreams. For the dream interpretation but not only the actual dream symbols are relevant. Also very important is the person himself e.g.

- gender and age
- the life situation
- Experiences feelings and thoughts of the previous day
- feelings and thoughts in the dream
- feelings and thoughts after waking up

Without taking personal circumstances into account dream interpretation is very difficult and superficial. The same is true of the meaning of tram symbols. The over 9000 dream symbols described in this lexicon can therefore only be interpreted generally. Some interpretations will fit relatively well on one dream others rather less. This should be taken into account in the dream interpretation.
