Precognitive Dreams / Is the Future Set in Stone?

This is a question to those who have precognitive dreams or visions, as well as open for philosophical discussion among anyone.

Background, i have had dreams of future events and places my whole life. Nothing spectacular like seeing 9/11 before it happened but definitely for fact i can say sporatically i have had clear visions of future events and places in dreams growing up.

What i define as this is, 1. I have a dream at a certain date, and, 2. I remember that dream, and, 3. Something from that dream happens in real life later. I define it that way in order to separate this phenomena from deja vu, which actually is another occurrence that has plagued me my whole life and is a totally other conversation in itself!

On to my point of this thread:

Early this year, i had a dream which i knew to be precognitive. In the dream i was working at a different company than i currently was and i was shaving my hair to a buzz cut. When i awoke i immediately knew it was precognitive and got somewhat concerned because i really enjoyed where i worked and also i did not want to shave my head. I was doing service call electrical work, so to maintain a professional appearance i kept my hair in a crew cut, parted to the side. In the past, i would buzz my hair to save money and avoid the florida summer heat.

Anyhow, a week or two after that dream covid19 shut down my state and i lost my job. This prompted me to do an experiment:

What if i refuse to shave my head? How set in stone was that premonition?

So far, i haven't shaved my head and i am in fact letting it grow out to prove a point- that i am in control of the future and it notnot set in stone.

Does anyone have thoughts on this?
