Yes, what you're describing is a common phenomenon known as the "McGurk effect" or "auditory illusion." It occurs when there is a mismatch between what we see and what we hear. The brain combines information from both sight and sound, and sometimes, the visual information can influence how we perceive the auditory information.
In the example you provided, if someone repeatedly says "Sandra" while you are looking at a picture of a panda, your brain might start to integrate the visual input with the auditory input, leading you to hear "Panda" instead of "Sandra." This effect highlights the strong connection between visual and auditory processing in our brains.
The McGurk effect is just one example of how our brains can interpret sensory information in a context-dependent manner. It demonstrates the complexities of perception and how multiple sensory inputs can interact to shape our experience of the world.
