Do thoughts influence everything? Or is this an illusion? What does Buddhism think about/or is it accepted in it that we influence everything with our (un)conscious thoughts and emotions and impressions (because these are also some form off thoughts right?) and can't not influence the universe we live in. Lately I have the fear that my thoughts influence everything around me and happening in my live. Last night I couldn't even watch a movie because I was paralyzed by the fear or thought of having a negative influence on it and making it worse. Then I came to the thought that maybe our universe is refreshing every millisecond and that everything we do or think generates another outcome. 

The thought is making me crazy because this would mean we have an immense responsibility on ourselves that everything we do does has an influence. I have this fear lately sometimes to watch the live news also fearing that I might in some way influence the newsspeaker with my nervousness. I can still imagine that this all is BS and not true. But there are so many weird impressions that I've had that my awareness like when watching a movie does have an effect on the scene. Or is this all an illusion and I'm I suffering from delusions? Also does Buddhism believe in different dimensions? And also Buddhism does accept consciousness is non-local right? So it's entirely possibly that my awareness does influence a news speaker?
This is a very interesting question.

In psychological interpretation of Buddhism, our perception of reality is mediated by our mind's modeling and representational activity. In this perspective the state of our mind - our biases, preconceptions, emotional condition - form the interpretative/evaluative framework through which we perceive reality. This perception of reality then determines our reactions and choices, which lead to immediate and latent effects (karma). This works as self-fulfilling prophecy or a self-reinforcing vicious circle: negative mindstates => negative interpretation => negative action => negative effects => negative mindstates.

In ontological interpretation(s) of Buddhism the structure of reality is understood to be different from what we normally assume, and its relationship with mind is not just that of modeling and observation. 

In one such interpretation, reality consists of multiple planes ("realms") between which we can shift depending on our state of mind, each of these realms looking like a complete world with its own consistent logic. In other interpretations, reality is either multidimensional or quantum, with our mind either able to change the focus along the extra dimension(s) or collapse the quantum function. In yet another interpretation there are no fixed planes as such, and whatever we perceive is assembled by our minds from some sort of multidimensional strings of energy.

As far as I know, there is no one who seems to be able to explain exactly how this stuff works... Two of my Buddhist teachers insisted that reality is literally a reflection of our mindstate. In other words, they claimed that Buddhism is not a psychological metaphor. One of them alluded to the "multidimensional worlds" interpretation and the other mentioned "multidimensional strings" - but none gave exhaustive explanation. The other Buddhist teachers I interacted with or studied under, remained ambiguous on the matter. Most of the time, the attitude I get is: "it does not matter what it is as long as you know how to navigate it."

The Buddha himself remained famously ambiguous on the question with his Safe Bet theory:


  "As you have not found an agreeable teacher, you should adopt and practice this safe-bet teaching, for this safe-bet teaching — when accepted and adopted — will be to your long-term welfare &amp; happiness.
  
  If there is the next world, [karma, causality], then this venerable person — on the breakup of the body, after death — will reappear in a good destination, a heavenly world. Even if we didn't speak of the next world [karma, causality], 
  this venerable person is still praised in the here-&amp;-now by the observant as a person of good habits &amp; right view. If there really is a next world, then this venerable person has made a good throw twice, in that he is praised by the observant here-&amp;-now; and in that — with the breakup of the body, after death — he will reappear in a good destination, a heavenly world. Thus this safe-bet teaching, when well grasped &amp; adopted by him, covers both sides, and leaves behind the possibility of the unskillful.


From my personal side, I used to be an adherent of the psychological interpretation for many years, until some recent events in my life that screamed of the ontological interpretation. So now I'm a bit uncertain myself and am sticking to the Safe Bet until I can figure it out. Or I guess, I think I know the answer (it's ontological) just not ready to fully accept it yet.

In response to your concerns about your mind affecting the universe or the newsspeaker etc. I suggest that you stick to the Safe Bet and try to eliminate this worry and these negative states of mind. If there are no other dimensions, you don't want to develop a psychosis that will turn your life in a nightmare through the mechanism of vicious circle. And if there are other dimensions, you don't want to shift to a bad one by being negative, are you? ;)

I hope one day we will figure it out. Until then, let's stick to the Four Right Efforts:


  ... monks, you should apply effort toward:
  - non-arising of bad, pathological states of mind that have not yet arisen.
  - abandonment of bad, pathological states of mind that have arisen.
  - arising of wholesome states of mind that have not yet arisen.
  - maintenance and development of wholesome states of mind that have arisen.
