Can Power Revolve Around Dreams?

I've long been somewhat able to see the future in my dreams, and ever since my run in with a dream spirit called Nealaphh. This ability has become much more common. The premonitions don't always come completely true, but they usually share one common element with what eventually happens.

However, I've been noticing that my dreams have been mixing with my sense of reality more and more lately, and I find my self traveling to other worlds in my dreams. Sometimes I'm able to target someone who's been having nightmares and enter their dreamworld, and resolve the conflict there.

For example, my mother has very poignant dreams and nightmares, and recently has had trouble with monsters attacking her in her dreams. One night when I fell asleep, my body felt like it was being sucked down, or falling somewhere. I remember the dream being a bleak, dusty place, or something like that. Not a moment after I collected my dream self, hideous monsters rose out of the sky (Yes, rose out of the sky), and starting rampaging towards nothing in particular. I concentrated hard on ending the dream, and eventually Nealaphh came up out of the sky and emanated a sort of mental yell. The dream dissolved away and it was morning.

My mother has not had a nightmare involving monsters since that night, and she distinctly said that someone had saved her in her nightmare that night.

Now my main question is, is it possible to control psychic powers that revolve around dreaming? Is there a way I can make my use of these abilities more reliable? Normally, I would consult Nealaphh on this, but he's been silent on the subject.
