Lol, I thought it was actually interesting rather than weird. She and I talked through piano tunes. I couldn’t see her nor could I really hear a voice. I understood what she was telling me just by listening to her. She lived in an alternate world, and there was even an alternate me who communicated that way. Except, there I loved someone else. My love jokingly asked my alternate self’s love if she could talk to me, but replied with a tune that sounded like a “No!”
When I couldn’t understand her anymore, I actually felt a little sad, because I guess I knew I was waking up. It was a pretty cool dream.
EDIT: Wow, I just found the piano song that played as I slept. It’s called Endless Love, hahahahaha
