Submitted by: Alison
I am 19 years old this year. During that time in 2002, sorry as i can't remember the date.
When i was sleeping in my bedroom with my sisters at midnight, i feel like something there, so i open my eyes, what i see is a lot of orbs in motion flying in my room.. but that is blue colour, it there any orbs blue?? or is that spirit? i never know what is that till last night i view this webside.. that night i never sleep again after it.. Wel, have a lot of experience at seing ghost since i was young.
The most i saw is "human look" type.. At school, apartment, hospital, grave, even during the dealth ceremony...
