Dream About Oblong Sac Egg Yolk

I pinched my nose to remove what I expected was a snot. What came out was an oblong shape sac with egg yolk like consistency. The outside of the sac was dry. I placed it in my pocket for safekeeping. Then I woke up and told myself that I need to enter this in my dream app. But that was a dream within a dream. Then I woke up and realized that, that was a dream within a dream within a dream.
