I have been in the 911 biz for over 22 years. If a caller starts the call with "I swear I'm not crazy" then you need to buckle up for some insanity. A guy started a call with those words after escaping from his apartment and running to the closest 7-11. He swore that his roommates were turning into giant crabs. The was going to show the officers that they were currently in giant cocoons transforming. As you might expect he was tripping balls.
