Do Ghosts really exist ?

Do Ghosts exist ????

I am blogging this today due to an incident which happened yesterday .

After coming back from office i was really tired .

But as i got the habit of watching tv before going to sleep kept me awake .

It was around 2.30 in the morning . I was half way to sleep .

Really sinking half way i heard some one knocking the door .

It was clueless for me .

I was wondering who is knocking the door at this time .

I could not find who is standing outside through the door hole as there was no light outside .

I tried to switch on the light outside , but its not working .

Then i dint have the guts to open the door.

So i just thought if its some one they will knock again and then can see what to do.

I was not scared at this moment .

I was alone , as my parents have left 2 days back for a marriage function , and will be back only after a week

I made sure all the doors are closed and came to tv room , as i planned to sleep near tv , so that in the morning i can wake up soon .

I was slighty sleeping ...

Suddenly .....

Bang Bang Bang ...

and a kid laughing loudly ....

I just jumped ....

Goose bumps out of scareness ...

Was it from TV ?

Or some kid in the flat ?

But it was like right next to me ...

At this point of time i was scared to the core .

I was just thinking , please the current should not go off ...

I went to make sure the doors are all closed properly ...

It was closed , and the tv is already switched off ...

I had no clue what that sound was ....

But the knock of door was heard 2 more times when i was trying to sleep ...

What could it be .....

Morning i searched the internet about ghosts and found many freaky topics ...

But i dont know ....

Do Ghosts really exist ?
