Now I’m thinking about it, “make sense” to not have sound in your dreams. As your eyes are shut down, keeping your ears available to detect danger seems an advantage to be selected. And that fits with my experience where the sounds I can remember were real.
But there are others known examples of sound inside dreams: musicians! Many songs were written in dreams:

OP, it’s fine to believe in whatever you feel like it, and IMHO ghosts and aliens are better beliefs than some other options.
With that said, I think it would be better to say that you believe those things and use the “not 100%” as a justification.
There is no way to gather all evidence about any topic, so we need to define what is acceptable as “enough” evidence and what “make sense” according to what we know; at least when we (as a society) talk about science.
It’s hard to express, but an example is the feeling that you suddenly know something, got an idea, an eureka moment. I’m saying that all thought is like that, but less… intense. And we use language to “register” that as what we usually call “think”; but we don’t need language to do that, it’s just easier with it.
“Ethical consumption” is fine, but have a very low impact: Most of environmental damage is related to corporations, not by population.
Information is key: To solve any problem, we need to understand it the best we can. So how climate change works? How human action is driving it? Who is responsible? And what are our options? Look for science communicators that reflect the scientific consensus, not the opinion of a small group.
Be aware of/with any “solutions” that is proposed by or also benefits big corporations and the billionaires that owns it. There is a lot of green-washing shit around.
Vote for politicians that have a solid green agenda. Votes matter, but in capitalism, it is not enough. The capitalist system is built to maximize profit over everything else, that’s what will happen if there’s nothing stopping it to happen. So political education and engagement makes difference.
