Few weeks back i had a very different dream while sleeping. I never fantacise having sex with my elder sis.
I had dream she was next to me and we had kissing. It was very different and deep sort of lips kissing. Was very close and different like on soul.
I look up what it could mean and the site I checked said this: “Brother or sister: If you kiss your brother or sister in a dream it may represent your special bond with them. It may mean that the two of you have a good relationship.” So I think it only means that you care for your sister very much and that it.
