What does it mean when dream of dead person and they are saying come on?

The meaning of this dream depends on who the "dead person" is. The category of "dead person" is so huge that a meaningful answer is very difficult. A dream of a beloved, recently deceased relative would be very different from a dream about a threatening zombie, a repulsive corpse or someone long dead historic person such as Queen Victoria. Generally speaking, during the period of mourning, it is entirely normal to dream of the deceased. These dreams represent the dreamer's feeling of loss and sadness.

> Dreaming of a deceased friend or loved one beckoning you or calling you to "come on" in the dream can be disturbing, but it is not unusual. Such dreams are caused by your own feeling of guilt or remorse simply for being alive while the other person is dead. The dream is produced by your own mind as you struggle to deal with the painful mixture of grief and guilt. The dream is not predicting your own death or placing any blame on you.
