Well after i had talked to her then next day she knew everything about the dream and the keyword. I don't really talk to a lot of people about LD's and especially not her. She said she had one other dream similar to it in which she knew that she was dreaming but woke up immediately (so, a layer 1). So i guess you could say she wasn't very familiar with dreaming. So i guess in conclusion we both had the same dream at the same time. Amazing right!
