Very Loud Boom 6:50am cst

[Iris]

I've had difficulty recalling my dreams this past week. At 6:50am CST I woke up with a bolt after hearing an extremely loud boom in my dream. I don't recall much of the dream. I was with several others, we were outside on a sunny, mild day and either digging a large hole or looking at a large hole (6 to 10 feet across). Suddenly the large boom. I did not see or feel an explosion. I woke up with my heart racing. I do not recall ever having a dream like this before and it seemed important to log along with the time.

Emotions: calm, analytic then startled at sound
