Use that to your advantage.

Kind of what above anon is referring to. Not like I know for sure, it's anecdotal. But the few I know who have gotten into manifestation + related areas, pretty much anything that tests your mind's ability in terms of control over time, space and the physical world, they tend to be able to do so faster/to a larger degree. 
Again, no expert but it's gotten to an undeniable point for me, and my hunch is that it's due to a naturally shifted perspective on reality to begin with.

What exactly have they done?

2 only decent examples I have besides myself: 
Guy I did not know IRL, but spoke to and saw pictures of throughout process. After lamenting that he realized he didn't look how he 'pictured himself' in his dreams, he just decided he was going to start staring at himself in a mirror in his dreams and note what needed to be changed. Apparently this took time because the process would freak him out and wake him up at first. But once he managed to get used to it, he explained it as being able to watch it change in the mirror like a time lapse of sorts. Fucker managed to grow 4cm and go from pathetic patches to full-fledged beard, among other things, in about a year. Took pics of the whole process as it happened. It's not unheard of for a guy in their mid-20s to have a puberty-like change but it was pretty uncanny that it happened as he just...decided he wanted it to. His physique also completely changed, to the point where I asked if he had been taking HGH or roids or something. He wasn't, but I won't include that because he did start doing pushups everyday. Still, that was his only real change in habit, according to him. 
Another was my friend I knew IRL in college. Us discussing this is why I came to this conclusion about autism and 'bendability.' If someone pissed him off enough, one of the people closest to them would die in less than a week. There were rules to it - he couldn't just 'pick' a person, he had to get legitimately annoyed/angered, and this had to happen in-person. But while I was friends with him, I can remember 3 times in which this happened like clockwork. Was usually either one of their parents or friends, not an elderly relative or something.

I should add that it took a long time for the latter friend, to accept and make use of this. It traumatized him so much as a kid he was afraid of people getting near him, because he didn't know if they'd do something to anger him and he considered those deaths his fault. He had kinda gotten over that by the time he was in college though, guess as he got more emotional control it got better for him.

In The Occult by Colin Wilson, a landlord has the same problem as you friend. I also have this problem. I've had it since I was about 12. People would upset me and terrible things would happen to them-injuries, sickness, death of a loved one, and one direct death. By my last count, 8 people have died and countless have suffered calamities. I would often try to reason that it was just coincidence but it became so specific over time that I could no longer convince myself. The best theory I have is that some people can subconsciously cast the evil eye on people. Does your friend have green eyes by chance? That seems to be common among whatever we are.

Lol I suspect I'm an aspie and this has happened all my life. If I really hate someone, something happens to them eventually or they move far away from me. 

Happened to all the teachers I hated in school. Like 4 of them, just got up and left a month after I decided I hated them.
