Woah that's so awesome, that's exactly how He spoke to me! I thought it was a sibling, but the voice was different, it was gentle too! It's incredible hearing His voice audibly, or audibly to us anyways!! I was blown away..I too did not respond to hear what He wanted to tell me, and it made me so upset. I love Him so much...Yes, friend your not alone, your not crazy, Our Lord spoke to you, and He did it in a beautiful way, you are precious to Him, God bless.
