Dread = Creativity

Anybody in a creative mindset, whether that be writing, music, cooking, etc., every time you're digging for creative ideas, does your brain ever think embarrassing thoughts? Like, when I make beats, I tend to make beats based off of my emotions or how I'm feeling when I make them. However, sometimes I cannot finish a beat because my brain musters up something embarrassing/despondent from my memory vault. It sucks because I don't want these past memories to ruin my creativity, but sometimes the anger and embarrassment truly do help or hurt me. Any tips?
