"Woke up" in my dream.

Date: 12/12/2017

someone I recently befriend texted me and I woke up to a text that said:" Nice hanging out with you, Friend C told me to give you hugs (Greetings)" And I saw that my only reply was:"..........." She also replied:"......" and then:" okay, thanks." This was all in my dream, but I thought this text was real. I couldnt understand why I would only go:".........." So I while attempting to text her back telling her I must have fell asleep, implying I wasnt going to leave it at:".........." which still didnt make sense, I actually woke up, still confused I check my messages and there was nothing there.
