Subconcious Psychokinesis?

Does anyone know if it is possible to somehow subconciously influence events?
This happened to me many times, although most times i assume its just a weird coincidence because the conditions are relatively simple.
- i would think of a person i havent talked to in at least a year, and within the minute i would receive a call/IM from them
- i suddenly found myself broke and in need of money, so i thought how lucky i would be if i found some, and then a few blocks later while walking, i found 90$
- i was working, and i work in an arcade, and i was really agitated and didnt want to be bothered but it was really busy and understaffed. so when i went to help a lady with a mundane but irritating task, i said in my head jokingly, "tipping is customary" and she did tip me, something which rarely happens in an arcade.

these small events always seem to happen sporatically, but if i ever conciously try to change or influence something, it never happens.

Am i just really lucky and all these things happen by coincidence?
