I agree with what Sageous said. ^^

Since you now know some of your dream signs, you can do a reality check everytime you see them, or are in them, or even everytime you think about them or they cross your mind.

Sooner or later, you will reality check while you are dreaming, and you'll hopefully get lucid. Remember to really put thought into your reality checks though, and really think about it.

Good luck!
