Déjà Vu is the feeling that you have already dreamed or done something that is currently being experienced. Like you've been in the moment before. Most people have experienced it, but have you felt the opposite?
Researches are calling this phenomenon "jamais vu." This situation is when you feel totally disconnected to something that is very familiar to you, as if you've never encountered it in your life. Like driving home from work and all of a sudden the roads seem unfamiliar.
Have you ever experience Jamais Vu?
