Her family was nearby discussing her condition.
The sun was changing orbits, getting closer and closer to Earth. The family was worried about breaking this news to the girl when she woke up, about the earth getting closer to the sun, not knowing about the girl's dream. The girl woke up from her dream and the parents had to tell her, she wasn't freezing, she was boiling. I'll tell you, those shows were more scary than the 'best' horror show hollywood produces today.
A particular favorite of mine was "Uncle Simon."
