What does a tattoo in a dream mean?

I tried looking it up myself, but my dreams are so frigging random
I usually don’t care but this time it’s bugging me. I can’t firgure it out. The most important part I wanted to know about was that I was looking in a full width mirror in a bathroom. They go wall to wall. I could see a tattoo on my back of my abdominal cavity. Lungs, heart, veins, intestines, stomach, the whole thing. It was iridescent or had a gold glow to it. Everything else was in blue and red, except my intestines, which were more white-ish. It covered my whole back.

I understand that this gets asked a lot, but could someone humor me? I’d really appreciate it.
