I had sex with my bestfriend and I killed her afterwords
Dreams about sex and violence can be disturbing, but they often symbolize underlying emotions, desires, or conflicts in the dreamer's waking life. In this dream, having sex with your best friend and then killing her may represent a complex relationship or power dynamic between you and your friend.
Sex in dreams can symbolize a merging of qualities or aspects of yourself with those of the other person. Killing someone in a dream can symbolize the desire to eliminate certain qualities or aspects of that person, or it can reflect feelings of anger, resentment, or betrayal.
It's important to consider the emotions you felt during the dream and upon waking. Reflect on your relationship with your best friend and any unresolved issues or tensions between you. This dream may be a manifestation of subconscious feelings of guilt, jealousy, or a desire to assert dominance in the relationship.
It's also worth noting that dreams are highly personal and can be influenced by a variety of factors. If this dream has left you feeling unsettled or confused, you may benefit from exploring these feelings further through journaling, therapy, or open communication with your friend.
