As a general rule having a phobia is abnormal, hence it being a phobia. But you're not alone. A Google search has raised a few similar questions. I also have a phobia of sleep walkers among other fears relating to sleep. But there is no name for it. Even looking for a solid name for a fear of sleepwalking leads to a fear of sleep.
In short, if it's severe enough and abnormal it usually qualifies as a phobia.
