The Ghost In My Wardrobe

Either I'm going insane and keep leaving one door of my wardrobe open and forgetting I've done it, or I'm being haunted. I keep walking in after I'm sure theres no reason for my wardrobe door to be open, and like 50% of the time, my right hand wardrobe door will be open?! But only ever the right hand one, it would appear I've got a very picky ghost. Or whats most likely is the stress of looming deadlines in sending me insane. Who knows.
