Real, the reason is that after you ears recieve sound and convert it to signals it gets decifered. If someone doesn’t speak clearly enough it takes time to be decifered. I’m sure you experienced this yourself.
The same can happen with eye sight. When you find yourself suddenly in completely new surroundings it takes time for the scenery to settle into place.
Your brain gives you words and objects, and that’s what you remember — unless you’re an artist.
