Hallways

You may find yourself stuck in a building that seems to consist entirely of hallways. First of all, don't panic. There is only a moderate chance anything will hurt you, and you may even be able to make it out someday. 

Now, of course, you are going to panic. That's normal. But seriously, don't. Don't scream or shout; nobody who can help you is going to hear you. There are things that will hear you, but they are not going to help you. 

Do not run blindly down hallway after hallway, through corridors and passageways, up and down the galleries, concourses and antechambers. You will only tire yourself out and be unable to run when you really need to. 

There should be food and water here, somewhere. You need to move efficiently and steadily. Travel for ten minutes at a time. Stop. Listen. Move again. You'll either find it or you won't. Sleep when you need to. You'll startle awake. When you do, do not try to go back to sleep. Continue moving. 

If if IF you find a door, kick it open and then run and hide. See what comes out. 

If nothing comes out, wait some more. See if anything heard you kick the door open and tries to go in. 

There isn't much more to it. 

If you do this long enough, and get very luckily, you might get out. 

But don't bother telling anyone about what happened. They won't believe you.
