People tend to entrust their own dreams, hopes, wishes or aspirations associated with past positive or negative experiences, to others. These “others” may include children or people in younger generations. To date, psychological studies have investigated several developmental characteristics in relation to time perspectives. However, few studies have focused on the influence of personal experiences in perceiving of images of future perspectives and autobiographical memory on abandonment or entrustment of dreams. The present study examined the influence, based on the data of a total of 309 undergraduates for two questionnaires including open-ended questions and rating scales. The questionnaires examined,（ a） the kinds of feelings and reasons that occurred at the time of abandonment and entrustment of dreams, （b） the personal experiences prompting the abandonment and entrustment recalled, and（c） how current images of future perspectives conveyed sentiments that dreams should be entrusted to someone else. Statistical analyses of the data revealed that specific aspects of time perspectives and autobiographical memory were strongly related to participants’ feeling of entrusting dreams to the others.
