I've had a very few dreams in the past in which I was kissed on mouth by some invisible force or some celebrity or some stranger. Each of these dreams felt so real and powerful. I could clearly sense their lips and tongue. I've never kissed anyone on mouth in real life but I have an idea of what it must feel like. The one with invisible force was very powerful. Was I kissed by someone in astral plane (According to this guy (belsebuub.com/articles/experiences-in-dreams-and-in-the-astral-plane), we visit astral plane in our dreams) or was it just my brain?
