Answer 1

Ever wonder why you see stars when you rub your eyes? It’s because you’re actually pressing on the light-sensitive cells in your retina. When these cells get squished, they send signals to your brain that look like flashes or dots of light, even though there’s no actual light there. It’s like a little visual glitch caused by your fingers.
