A team plans a partial replication of Williams et al.'s (1992) study. Participants will spend one night in a sleep laboratory while attached to monitoring equipment and will record their dreams there. During the following day, they will also record waking fantasies. Before using the bizarreness density scale, the three judges will be told whether each report is a dream or a waking fantasy.
Explain two reasons why findings from the planned investigation might be less trustworthy than findings from Williams et al.'s original procedure.
