Can you actually share dreams?

I’ve had about 5 what I believe to be shared dreaming experiences. Most at the request of my DG. The difference in those 5 dreams was 1.My view was 3rd person instead my usual 1st person and that is rare for me. 2.It was always assisting someone but no one I knew or even had the feeling I knew. I felt someone had called for help and I responded to assist. 3. The “feeling” was different. I was feeling the emotions of both myself and the person needing help. After I had…led them out of the building or fought their monsters, they just faded into smoke. I think “Dreamscape” is the best movie ever for training and things like this I felt.
