Dreaming of a sibling may represent that you’ve found a guide to bring you to your deepest Self. So, you can more easily resolve the problem that is worrying you. The oneiric images of the sibling is, for some superstitions, a sign of betrayal and hypocrisy.
Sibling
Siblings symbolize very clear tendencies in your personality. Dreams in which siblings appear—although the dreamer is an only child—foretell the need to integrate certain qualities that the dreamer lacks and are necessary for communication with others, into their deep Self. Consequently, this dream is trying to say that you want to find someone to share experiences with. Additionally, you must keep in mind that traits or defects we don’t like to accept in ourselves tend to be projected on siblings. In this case, a correct interpretation can be very helpful to know yourself better.
