Could dream sharing be linked with multiple interacting consciousness?

I was pondering over this the last few days and doing some basic research so I thought I would share with you all and find your inputs :)

Okay so here recently I've become very interested in what I call conscious interactions... I don't know if there is a specific term for this, but it is when your conscious interacts with someone else. I'll give a few examples:

1. You are beside someone talking about something, or doing something together. Somehow, an irrelevant topic both comes up in both of your minds, via reference or another resemblance. Like when something pops in your mind, and the person you are talking to brings it up.

2. Yawning. Now this is something you can experiment with yourself. Try to notice when somebody is looking at you. This would show they are thinking of you. Now yawn. There could be multiple people around you, but only that person would yawn as well, even if they hadn't noticed that you just did.

3. When two people do the same actions as they are conversing, such as clearing their throat.

4. There are some stories of mothers (you can google it) that have sensed there child in danger, and without notification, actually knew about it (causing them to travel to where they are, call them, ect.) [Child thinks of mother, mother thinks of child simultaneously]

Now how does this relate to shared dreaming? What if, two conscious had an interaction while both people were dreaming/sleeping. Perhaps they would both morph into one dream, creating a single dream for both consciouses.

Now you could be thinking, "Wow, thanks for finding this scientific discover Captain Obvious" Of course shared dreaming would have to come from two different dream creators, aka, conscious. But what this thread is really trying to say. How can our consciousness interact without both of them trying to make a connection? This would bring me to the conclusion that:

Shared dreaming can only occur when both consciousness contact each other specifically simultaneously.

Therefore, you can't have a shared dream if the other conscious is not trying to contact you as well?

What are your thoughts about this? Do you think that shared dreaming is based on my conclusion?

You probably find best answers to this in existing threads on shared dreaming. There is a lot we don't know about our minds, so I guess, anything is possible. Happy dreams :)

Recieveing and transmitting information between the two minds is possible to some extent while awake, through actions such as yawning and body language(as you said).
However, i cannot see how this is supposed to happen efficiently while asleep(maybe sensing the movements of someone lying beside you in bed?).
I think it might be possible for two persons to have similar dreams because of their influence on each other, but syncing the dreams is probably impossible.
I do not believe in shared dreaming.
