A spirit of perversion, Lev. 18:23
To dream of participating in bestiality with an animal larger than yourself indicates a feeling of powerlessness within a sexual relationship, and an unconscious desire to dominate a partner whom you believe is more powerful than yourself. Dreaming of dominating an animal smaller than you may indicate a power imbalance in your intimate relationship that you are not comfortable with.
To dream of watching bestiality and enjoying the experience may indicate a wish to ‘tame the wild beast’ within yourself. Dreaming of bestiality in any form shows a personal power issue that is on the verge of being resolved.
