tell from the facts you provided. Many more details are required. For example:
How long were you there?
Whether the incident report was generated or reported to a law enforcement agency
Whether it was a school (i.e. non law enforcement) issued report.
What prompted the report--abusive behavior, language, loud music
Whether minors were involved and a long list of other factors.
Recommend you read the fine print on the documents you received, look for what it says the consequences are or can be.
Next, check the university's website, see if you can locate housing/dorm policies and possible consequences for off campus visitors.
If your are charged, contact a local attorney (criminal defense) for representation.
