Fear of the unknown

For the longest time I haven't remembered a dream I've had once I wake up. But the night before last I had a vivid dream of holding a new born baby in my arms and naming him Carl (after my grandfather) The one thing I noticed about the baby was that it had a full head of dark hair. Just like all my babies did. It's physically impossible for me to have another baby, this dream scares me and has been haunting me ever since.
