Hey footballFred- I’m not sure I do. Sometimes I think there must be something bigger than the world we live in- something that knows all of the answers to the questions before we ask them. I often hear funny noises in my house, and think that if it is a burglar my dog will protect me- then I remember my dog actually just likes company, so he will probably just hang out with the burglar!
I hope if there are ghosts they are as friendly as nearly headless Nick in Harry Potter.
I think that ghosts are extremely interesting. There are a lot of weird things that magnetic and electrical can do to the way our brain works. Pollutants like carbon monoxide have been shown to produce both visual and auditory hallucinations.
However, I think that we don’t understand very thing and as a scientist we should not rule out anything until proven. Absence of proof, is not proof of absence.
