Lift daze

Have you ever got struck by lift daze? What is lift daze? It is when inside a lift waiting for reaching your designated floor, you suddenly seems to lose your sense of direction, or so to say alertness. When the door opens, we would usually be moving towards the opened door, not aware if the level is the correct level or not. So even if the sound system in the lift would announce the floor number but it seems somehow blocked from our ears. Lucky for us we got alerted to the actual floor before the lift door closed. So other then being embarrassed it just seems to happen again over and over. So how is it that the lift could dazed you? I am still being stuck once in a while in the lift in my work place. So I make it an effort to concentrated and think of nothing until the lift opened with the correct floor. Maybe taking the lift isn't for the weak minded.....
