Nonsense dream, please help me XD

I was with some buddies of mine in a green space surounded by a few trees and bushes. These buddies of mine are the ones from my childhood...so I've seen them as kids and so as I. Anyway...they asked me to take a picture of them and I did...then we decided to look how did the picture look like and there was another person in the picture beside them and this person is actually my grandfather who passed a few months ago. I remember the way he was looking like in the picture and he was pretty much happy. Somehow, my buddies didn't say anything about the picture so I told them that it's their turn now to take a picture only with myself. After the picture was taken, as usual..I wanted to see how did it looked like and it looked like a skull...then it started to go "full-screen" in my mind....


It was 40 % similar to this one...

However, I have something else on my mind that I'd like to know what is it about.

So...in the past years I have moments when my view is turning black for a couple of seconds and then slowly it dissapears...it starts the same way...slowly comes from both sides (left and right) like darkness untill my whole view is black and sometimes it has a reddish color with pink and dark yellow....

When your view turns black, does that happen when you stand up from sitting or lying position?

Yes, it does.

I don't know what else I could say about it ...

I have that too, and I know some people who also have that. It's nothing to worry about it. I think it has something to do with your blood circulation.

Long story short, when you are at rest your veins dilate and become larger. Thus making the "container" that hold blood in your body larger. When you stand up from a sitting or laying position, your veins can't compensate fast enough and your blood pressure drops. This results in lack of blood flow to your brain for a short period. The first of your senses to shut down is sight. With the part of your brain that handles light being the last. This is why it seems as though you are losing vision from the sides to a single point of light. As your veins begin to compensate and increase your blood pressure blood, oxygen and nutrients begin to flow back to your brain and your vision returns. Fighter pilots deal with this every time they go into a high G turn and they have flight suits that help compensate as well.

This is a common occurrence with many people. There can be a number of underlying medical issues causing it. But most often it's because you are dehydrated. Do you drink a lot of water? Or do you drink a lot of other stuff like soda, coffee, tea or other drinks like energy drinks that contain high amounts of caffeine? If so, increase your water intake daily and you will probably not have those episodes as often.

Great answer! Thank you so much, sir.

I will drink more water.
