Do u think my mom made this ghost story up!!?

So why would your mother make something like this up? I can understand how your mother can forget for a moment that your grandmother was dead. She was exhausted and was totally focused on her baby. She woke up and saw somebody so familiar to her and she didn't think nothing of it at the time. Dead is but a different level why wouldn't your grandmother come to check on her grandchild? Your mother was open to seeing her at the time. I am sure grandmother has been around allot more since then. What a great family p down story.
