Do ghosts exist???

I don't know if they do....haven't seen one yet. So i'm pretty much sitting on the fence here......don't know if they exist but i have an active enough imagination to freak myself out if someone narrates a convincing story!!! hehehe isn't that amusing.

Well let me tell u what's more amusing - have u heard of the ghost in some part of Gujarat.....who apppears each time Himmesh Reshammiya's song "Jhalak dikhla ja" plays!!! (hehehe i think he must be feeling, that they are calling out to him ) Apparently, it's no laughing matter, several people claim to have seen it and some even lost their lives it is said. But I can't help exclaiming at such a ridiculous story.

I've been trying to reason this dilemma out but... hmm u see my so called logical brain (that's what i like to call it, although i may have just contradicted myself, if u refer to the statement in para 1) has yet not found a rational explanation to prove their existence.

To investigate this subject further u would naturally come to ask the question "what happens to a person after death?" Now if you look at it from the angle of philosophy, one theory goes that the being which can be classified into 3 parts - perishes in the following way :
the physical or gross body - perishes to merge with the 5 elements that it is made up of
the subtle body which includes the mind and intellect - carries forth into the next life
the soul or atman - merges with the macro consciousness.

Now if u ask me, in all my very limited knowledge, i perceive a gap here - what happens to the subtle body between death and the next birth??? where does it exist in the interim?? The word 'subtle' itself conjures up the image of a formless, ephemeral substance floating around......reminds me of Casper!!! u know what i mean......

Is that an explanation??? may be may be not.....I'm still looking for an answer........any interesting theories?????
