No need to do RCs. All you have to do is remember that when you're sleeping and find yourself at work, you're dreaming.

You're already aware of your dream sign every night while you're dreaming. All you have to do to while you're dreaming is remember that being at work is your dream sign.

To do this, you set an intention to remember that when you're in bed and find yourself at work, you're dreaming. The stronger the intention, the easier it is to remember.

It's like waiting to catch a bus. Your wait for the bus, you anticipate for the bus to come, and try not to be distracted when the bus comes. If you're ready when the bus comes, you catch it. It works the same way with dream signs.
