What horror movie has spirits and people trapped in a house?

I can't seem to find this movie.. so I wanted to ask you guys.. I know it will be hard to find out the answer.. but here is the details... well it seems like there is a group of people, sort of in their 20's or so.. and they go to the big mansion i think.. and this girl is trapped in there because she is like mesmerized by these kid spirits.. i think she thinks they are like angels.. but they are really demons maybe.. not sure.. i remember this was probably like 8 years ago or so.. im not sure either.. but this girl i believe like was convinced and hypnotized that these angels, and they sort of looked like it were good.. and these other people were there to..oooo i also remember that some of them escaped this house and they found out that that girl was missing and they were thinking she was probably still in the house.. i am starting to remember a couple of things.. and i think someone lost an eye.. again im not sure but these things are coming back and I'm getting very irratated that i cant figure it out.. :( someone help.. ill see if the house on haunted hill is it.. but im not convinced yet..oh i forgot and those people were thinking about going back.. but they werent sure they shud risk their lives going back and i think some of them do go back.. i dnt remember if all of them did..
