Tendency to see novelty in mundane and trivial statements
Might apophenia be the term you are looking for?


  The term is attributed to Klaus Conrad by Peter Brugger, who defined it as the "unmotivated seeing of connections" accompanied by a "specific experience of an abnormal meaningfulness". Apophenia has come to imply a universal human tendency to seek patterns in random information, such as gambling.


Also, as mentioned somewhere above, it is commonly found in patients with schizophrenia.
