Dream meaning about a child telling them no?

CW// To some people, this may be disturbing to read. I don't know if it's really disturbing? Since can not remember the emotional feeling, just what happened.

This was a long time ago, but, still will use "we" and "him" language, It would feel more comfortable that way.

So, when he was like around 11 years old? He would have recurring dreams that follow the same theme, about being in some bright green room, like in a green room, sometimes other colors. So this guy, another kid his age, would approach him, and starts touching him in places, groping. And he would tell him to stop, and try to get away, and get him off, but can't.

Despite, the feelings of pleasure, he really disliked it, and not something he wanted. In other dreams with the same theme, he had a gun. But bullets turn into gum, and he still gets touched, and try to stop it.

Never really understood the reason, even I don't recall what even prompts these dreams, since I can't think of that child was ever stressed at all during that age?
