Most of my dreams are in 3rd person, where I'm watching myself, though it often switches back and forth. If you're lucid you can try controlling the person/people you see by just your thoughts. If you see yourself, you know that they're you, so just imagine what you would do. In the process you may find yourself back in 1st person, who knows?

Also, with spinning, it's just a technique some people use to make things easier. If you're in an FA (thinking you've awoken, but in fact haven't), once you become lucid you can use spinning to, in a sense, blur your surroundings so that when you stop you'll be where you want to be. Some people also use spinning as a way to try and start flying. You can also use other techniques to go places or find things, such as walking through a door or around a corner or having someone bring you/it to it/you. You just have to know that it will work... and it will. Confidence is key.
