Symbolizes the breakdown of friendship
This is the most common way to interpret the dream of a friend becoming a ghost. To put it simply, you have misunderstandings or conflicts between you and your friends in reality, which leads to hostility between the two sides, and the excellent relationship between relatives and friends will eventually become strangers.
This situation can affect your mentality so that there are various changes in your dreams. There is a dream that your friends have become ghosts. What the dream represents at this time is that you have been unable to reconcile before.
Symbolizes the health of a friend
It is also a relatively simple method of interpretation. Because becoming a ghost means death, so dreams represent the health problems of your friends, which makes you feel worried. This worry will be further expanded in your dreams and even the situation that your friend has died.
This is a manifestation of the continuation of reality. It is probably because my friend is currently sick and hospitalized in reality, or is suffering from a disease, etc., which has caused a change in my mentality, and this kind of dream has appeared.
Symbolize the longing for the dead friend
When your friend has indeed died of a serious illness or other reasons, then the dream of your friend turning into a ghost means that you actually have a feeling of yearning for your deceased friend.
