Perhaps you should try some spelling variations:
auditive halluzinationen » optische halluzinationen, echte halluzinationen, mit halluzinationen
zustande halluzinationen » und halluzinationen, sind halluzinationen, visuelle halluzinationen

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((auditive halluzinationen) OR (zustande halluzinationen)) ) OR ( auditory hallucinations )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((auditive halluzinationen) OR (zustande halluzinationen)) ) or ( auditory hallucinations ))".
• Adding a wildcard symbol may retrieve word variants: (( ((auditive halluzinationen) OR (zustande halluzinationen)) ) or ( auditory hallucinations ))*.
