My Sister was on Broadway

In a dream I had last night, my sister starred in a Broadway production and was a critical success. It was just something she tried out. I told her that she would most likely become a star now and get other gigs, maybe films. She said that her agent had said as much. She's actually a doctor, but she tried acting in this dream based on a favor someone asked...or something like that. I woke up disoriented. My room was very warm, and I had fallen asleep with my light on.
