To dream of receiving a telegram represents feelings about getting personal information or pertinent details that are very important. Feelings about being informed about something important or significant.
Negatively, a telegram may reflect your feelings about thinking it isn’t important to listen to something that someone else thinks is important. It may also reflect your overreaction to bad news.
A young girl dreamed of getting a telegram that said her father had died. In waking life she received a phone call the next day to tell her that her father had been injured in a serious car accident. The dream may have been an intuitive message that reflected her feelings about the phone call scaring her that her father was going to die.
