That We Are All Upside Down & When We See Summthing Our Brain Transfers It Backwards.
I Overheard My 5th Grade Teacher Telling Another Student That.
Could It Be Truee?

No. You did not hear things correctly. What she must have said is that the lens of you eye turns the images that strike the retina upside down and your brain interprets them as right-side up.
A single convex lens, like the one in you eye will invert the image if the image is beyond the focal point.

No, we're not upside down. What your teacher was talking about is that the image shown on your retina (the back of the eye), is inverted and reversed. This is normal, given the lens shape of the eye. Our brain recognises this and compensates. You never notice the difference.
A neat experiment often done in psychology courses is to outfit the person with inverting prism glasses (they turn the world upside down). For about half an hour, you will see things as being upside down. Then, without your noticing it, everything will right itself and look normal. Your brain has compensated for the inversion. When you remove the glasses, everything will look upside down for awhile.
This is referred to as "encephalisation" of the senses. This means they are mediated by the brain, not the sensory organ (the eye in this case). Reptiles cannot do this.

No - but yes!
We are not upside down but our eyes register the image upside down and our brains work out that thast is illogical and therefore turn the image back the right way.

Our eyes do invert the light and our brain does compensate.
This experiment illustrates this:
Shut your eye and poke it (gently) with your finger on a side.
You should see an effect on the other side of your field of view..

yes, it is true. especially related to our eyes, because they behave as a convex lens and transforms the image so that it is upside down

William D 's answer, I agree with.
