Question: Can your brain play tricks on you if so can it make you think you have seen a ghost and if it can have you seen one?

Good question! The brain can definitely play tricks on us and make us think we have seen things we haven’t….sometimes this is just a glitch in our brain processing, where we see a shape in our peripheral vision and think it is something that it is not..it’s just a hiccup in the connections in the part of our brain that process what we see through our eyes. An imbalance of important chemicals within our brains, which help the nerve cells send signals to each other, can also cause us to see things which might not be there.
