Do you have sometimes the effect of déjà vu?
When you just stare at something and trying to understand where have you seen it already before, even if you are clearly seeing it at first time..it’s a very weird and a bit scary feeling but I love it. According to hoomans, déjà vu was generally thought to be caused by the brain making false memories. But it's also possible that you just have better memory systems - which means you don't make memory errors in the first place. So if you experience deja vu and stare at the empty wall occasionally and your servant got anxious thinking that there might be a ghost in the house, explain to him that you just have better memory. Because cats are better than hoomans in everything, period.
