Hi. Was the man familiar to you? What sentiment did you got at that moment in the dream. As the place is prepared, it feel like this was about something that was done and not something that you will do in the future. Are you very religious? Anything reprehensible you suspected to have done?
I believe you recently have come across religion and or religious person. If you have not come across a religious person, then it relates to deeper feelings of sin or conviction you maybe feeling.
