I haven't heard of anything like that, and I definitely haven't heard stories of it being successful. However, if it is something that can be done, I wouldn't do it. Not because it wouldn't be safe, but because of moral reasoning. Messing with people's dreams (and therefore, their head) doesn't sound like the nicest thing to do.

I believe you are talking about dream walking. It's a thing that can be done. But i wouldn't recommend it unless both parties involved are consenting to the practice. Sometimes it can happen without meaning to just the sae as how one can astral project without meaning to. It happens. Otherwise I'd recommend respectful and mutual approach.
Depends on what your intent is and what your morals are. It also is a matter of your pools of Mana and your connection to the Dreamscape or The Forgotten Realm. Or really any place you draw power from.
