"If you can dream, you can learn it. Plus, since you don't have a soul, it's actually even easier and a bit safer."
"Grandma, what do you mean by that?" Wen Yan was getting more and more interested.
"Some people mess around. After they learn dream communication, they pretend to pass messages in dreams, but actually use it for Yin God invasion."
The reason they can do this is because, when dream-walking, it's really easy to bring in the power of the soul.
And if soul power is involved, dream communication starts to get invasive and triggers the other person's instinctive resistance.
But if there's no soul power, it's super safe for both sides.
So, when you dream-walk, you can only talk about things—nothing else can be done.
Likewise, even if the other person tries anything, if you die here, you'll just wake up in reality, that's all.
In the same way, dream-walking without soul power doesn't have that invasive bite—so it's the easiest to pull off."
