Dreaming about my DJ

Let me start from the beginning.
Me and my brother were staying in a very large house that i have never seen before. I am not sure why we were staying there, but it seemed completely normal at the time. I left the house that day to go to my job as a valet parker in front of an old movie theater ( old movie theaters are a huge reappearance in my dreams.) When i got back from work, i discovered that my brother had looked through my dream journal and made corrections through the whole book like he was grading it and mocking me at the same time.
I am not sure why i could not make the connection from my dream journal and go lucid; I felt like kicking myself this morning for that mistake.

Aw it happens. Just keep doing more reality checks. Why don't you do one every time you see your dream journal? It could become your dream sign.

Yeah, i was thinking that.
I should definitely starting using my journal as a RC just in case it happens to pop up in anymore dreams.
