Too Many Voices

I have been able to see and hear spirits for a long time now, but sometimes it feels like there are a thousand voices in my head all taking at once and I don't know who to concentrate on. It's frustrating because I know spirits are trying to talk to me and when it's one at a time, I can hear them but when this happens (meaning when I'm trying to sleep) I can't seem to separate the voice and can't understand any of them. It is just like being at a party and you can hear everyone talking, but you're not really listening to anyone so you don't hear what anyone is saying.

I go to a spiritual centre and have asked for help from mediums and others at my level, but everyone just tells me to explain to the voices I can't understand if they all talk at once, and that they will have to talk to me one at a time. I have tried this time and time again but they don't seem to be listening. This is also really affecting my sleep because it normally happens when I'm trying to go to sleep. It's like as soon as I relax, everyone who wants a word with me decides to show up all at once and nobody wants to wait their turn, they all want to be first.

Has anyone else experienced this and made it through the other side? I need help because my mum also has this problem and hers has got to the point where she gets it all through the day and I don't want mine to get that bad. Can anyone give me any advice on how to work out who is saying what and finally get a good nights sleep?
