I’m so sorry to see that people are sending you such negative replies. I believe you were truly asking a very real, very honest question. Anyone would be anxious after hearing a loud noise that is unexplainable! I do believe you should listen to your heart - if you heard this at the very time you were talking to your friend about God, it is meaningful to you. 🙏🏻 You can always talk to God and learn more and read. Please don’t be bothered by some of the replies. If this has stirred something in your heart you will know.
