When I was 13 just after I started puberty I began having fantasies and wet dreams involving my mom. In the dreams that I had it was so vivid and felt so real, almost like I was really inside her body that I would wake up from the dream covered in sweat and c**. I never acted on my urges but 23 years later I still feel a covet of shame and embarrassment that I find it hard to look her in the eye. How can I absolve myself of this?
