I have a lot of dreams where I become lucid and don't do RC's but I find I don't have full control over things unless I do. I have had dreams where I tell somebody I know that we're dreaming but wake up later and they tell me they weren't really in my dream. I believe shared dreams do happen though but likely aren't supposed to. My mom recalls that when she was little she had an extremely scary dream where she freaked out and pulled her sister into her dream to save her. My mother's sister actually remembers this happening, she was asleep at the same time my mother was having her nightmare.

Strong connections make anything seem possible.
