Do you drink a lot of coffee??

I do not really coffee as I have never really had a taste for it. But I would assume that coffee might affect people in this way because it contains caffeine. Caffeine is a stimulant and therefore has a number of 'stimulating' effects on the body's nervous system. That's why many people drink coffee to keep them alert. An excess of caffeine might make you 'overly' alert and maybe see or hear things that are not there. I could be wrong but that would be my guess

I used to have coffee twice a day until 2005. Slowly the want for the coffee reduced, and I completely stopped it. My office work also contributed to certain extent in this. I never had seen any ghost but sometimes, particularly at nights, heard strange sounds. (like people talking non-stop) I don't think that is because of coffee, because other people who used that particular room of my house have also felt the same. There's something with that room's location. My father was very fond of coffee and he never said any such experiences.

An excess of caffeine has different effects on different people. I've never heard of it being a hallucinagin, but I suppose it could effect some people that way. I did know that too much cinnamon could cause hallucinations.

Hey, very recently i have started drinking coffee and this is a new information for me. Hey, till now with my coffee experience my knowledge about Ghosts are only in words, haven't seen any due to this coffee cause, anyhow, I will keep you updated if i come across one :-), till then ghosts will be just an word for me.
