Something similar to Inception possible?

When it comes to warnings of Lucid Dreaming, I've only noticed one. I've read about people who mistake lucid dreams for their waking memory. So if you could actually create memories for your waking life and you couldn't remember if it was real or a dream could it be possible to preform a type of inception?

Dream sharing would be the case here. Although I have had 2 shared dreams in my life so far, nobody has been able to build the bridge from two dreams into one. I've heard of others who have shared dreams so imagine...

What if we could share a dream with another, act as a dream character and create a memory for whatever purpose such as fixing a conflict between the two people or adding a relationship flaw with someone else.

Also adding a memory would seem to be a bit harder than planting an idea, but could you imagine?

I feel like this could be very possible.

It's possible for two people to have the same dream. I've been in relationships with girls who constantly dreamed about having sex with me, so I'd guess it's possible. As long as you both talk enough to share the same mindset. Now fixing a problem would be hard, unless it's one you've solved before with the person. Then it is possible.

I believe it could be possible. I've had shared dreams before. So if your lucid and they think your just a dream character you may be able to fabricate a false memory
