To dream of being mediumistic would indicate that we are aware of greater powers than we believe we have in ordinary everyday life. When spirits appear in dreams, their function may be to help us through various states of transition. While we cope with everyday fears, there are many unconscious memories and feelings, which can surface unexpectedly. When we are conscious of a kindly or helpful spirit we are aware that we can move on. When we see the spirits of dead people we usually need reassurance.
