The topic says it.

I'm afraid my parents or my brother will find my dream journal so I can't really write down the weird/perverted dreams which make about 30%-50% of all my dreams. I need a solution here!

I mean, it's totally normal to have these dreams but written down they seem 10 times worse! They'll think I'm a psycho or something... Well, maybe not but still.

Should I just write everything down and hope they'll never find the Journal?

For example, in my last dream my mom told me that her and my dad had never had sex... (!) took me a while to think "Wait a minute..!"
