The source-monitoring paradigm suggests that dreams could be an important source of naturally occurring false memories. However, the malleability of memories for dreams remains to be investigated. The purpose of this study was to evaluate the impact of suggestions on subsequent dream recall. Immediate dream recall collected in a sleep laboratory was compared with long-term recall 1 to 2 weeks later. Standard recall was also compared with hypnotic recall. Suggested elements were reported by 15% of the 26 participants. The hypnotic condition showed no differential effect. It was also found that between 3% and 7% of the dreams reported in long-term recall were probably naturally occurring false memories of dreams. These findings suggest that situations of misinformation can easily elicit false memories of specific dreams.
