Being choked in my sleep by a spirit, possibly?

This is just sleep paralysis. It's pretty common. Many people say they awake during the night, unable to move, and a black figure or "The Old Hag" climb on their chest and choke them. I believe it connects with night terrors. I have night terrors but I've never had sleep paralysis. You can actually find out a lot about it if you search a little.

I believe in ghosts, but not in this case.It seems most likely that your family has a medical condition called sleep apnea. Apnea is a disorder disorder where there are abnormal pauses in breathing or instances of abnormally low breathing, during sleep. These pauses in breathing,can last from a few seconds to minutes, and can occur anywhere from 5 to 30 times or more an hour. To somebody with apnea, it might feel like they are being strangled in their sleep. Probably sleep apnea is the root behind the medieval idea of the incubus and succubus-- evil spirits that suck the life breath from sleeping men and women, See a doctor and have a sleep study done. Tell your family members to have sleep studies done; most insurance companies will pay for it.

All these people are wrong !

I know exactly the case !

What this is called is something that is rare . If you actually meditate you can see it . Whatever is attacking your family . Meditate inside the house and you can ask GOD for a Strong Angel to protect you through this journey. And well your meditating and you see it ask it why is it doing this. Does it only have in this that house ? If so then do the meditating

this often occurs when someone experience a sleep paralysis and probably the beings that inflicted those atrocities on your family were demons from world that lies in the darkest realms of darkness! as for not attacking you, I can't give you an explanation

They probably had sleep paralysis. It's a medical thing and no more related to spirits than having hay fever is.
