Well, I know that demons exist- I can say this from both biblical proof as well as unfortunate personal experience.
Yeaaaarrrrsss ago, when I was first joining FH, really, the paranormal really interested me, so my best friend and I tended to go looking for it- and ended up getting ourselves in trouble with it at one point. (I'd tell the whole story, but it's really long. XD)
Even still- though it's been years since then, and I know that I'm safe now because I have Jesus- I do feel that odd sensation when I'm in the dark or alone, that something is watching me- because I know something is.
More recently now than I did before, ever since the car accident that happened with my youth group a couple months ago that killed two leaders/friends and injured everyone else- that rocked my world upside-down, and obviously I'm sure Satan just loves using that to his advantage in scaring me and keeping me down.
Every now and then as of late I'll have really creepy dreams, where in the dream I'm just like- hovering above my bed area and watching myself sleep, but it has a dark feeling to it like I'm looking through someone else's eyes. Sometimes I feel like someone is standing right behind me, but no one is there.
Yeah, I guess you could say I've a lot of experience in this area than I would like to.
Demons are real. That's a fact whether we want to think about it or not. But I have reassurance that I am on the winning side since my God is bigger than the boogie man. ;3 My protection lies in Jesus, who even demons believe in and tremble.
I had a paranormal experience once and it was terrifying, I was at my parents bedroom because my bed was there too so basically we share rooms..I was there with my brother, jumped onto my bed and tried to sleep then I covered my self with my blanket xD after a while I started hearing some noises like a person is crawling on my parents bed (my parents were watching tv at the living room) I thought It was my bro, but it wasn't him, I was paralyzed XD until my bro woke up fast to see if someone's there and no one was except for me, I ran so fast to my dad and said " I ain't gunna sleep on that bed o.o" this happened so true :P also a few weeks later we noticed some small sized bloody footprints on my parents bed...so creepy , so yeah I believe on demons and ghosts..
We'll that took a while to type xD
