I would get a 1 meter square mat for the floor and spray ‘STAND HERE’ on it in a very bright rattle can paint. Maybe put some bumpers around the edge of it to prevent you from straying outside the square. Given your predilection for not knowing where you are, I might add some hazard tape to the perimeter of the square/bumpers, just to keep you focussed. Then, now this is the clever part, directly above where the 1 meter square mat is, cut a matching hole in the ceiling. You might have to make the ceiling hole slightly oversize to counter the reach of the neck when you remove it, but I honestly can’t see any flaw in this method.
