First I would like to state that I'm not about to begin to attempt such a act that requires a high level of experience in the art of "Lucid Dreaming" but I was thinking whether or not it would be possible to basically go into another's dream (such as a more experienced dreamer going into a noob's dream), and either start transforming it, or help the said person by helping them control their dream.

I also have a few other questions related to "Shared Dreaming" how is this scientifically possible? If you were to be able to connect to another's dream physiologically would you be able to talk to them without giving the illusion of you speaking vocally? By that I mean speaking to them just by thinking, but in real world, and dream world. Which leads to my next question, can you use this method called "Shared Dreaming" to technically invade others dreams by force as example in the thread named "Shared Dreaming - How to find other people when lucid!" you see her literally making a portal into his dream.

That's all for now. I'm sorry if this was a over load of questions.
I just want to find out the reasonings for this.

Thanks,
Kerl.
