Is this a lucid dream? Also what would be the best way to wake myself from a nightmare such as this?

water in your dream means knowledge. you are trying to learn from something. camera means trying to mirror your mistakes. a camera in dreams is capturing what had happened. and so you are trying to really focus yourself and learn. Something is stopping you to move on or make a good decision. But your dream means you need to really decide what ever it is. God bless you
