APOPHENIA is the experience of seeing patterns or connections in random or meaningless data. The term was coined in 1958 by Klaus Conrad, who defined it as the unmotivated seeing of connections accompanied by a specific experience of an abnormal meaningfulness.

• Pareidolia is a type of apophenia involving the finding of images or sounds in random stimuli. For example, hearing a ringing phone whilst taking a shower. The noise produced by the running water gives a random background from which the patterned sound of a ringing phone might be produced.
• “In statistics, apophenia is called a Type I error, seeing patterns where none, in fact, exist. It is highly probable that the apparent significance of many unusual experiences and phenomena are due to apophenia, e.g., ghosts and hauntings, EVP, numerology, the Bible code, anomalous cognition, ganzfeld hits, most forms of divination, the prophecies of Nostradamus, remote viewing, and a host of other paranormal and supernatural experiences and phenomena." – Robert Todd Carroll
