Sleep paralysis? Anyone with fibro find this a problem?

Hi guys, does anyone else find that when they sleep they feel like they are sort of in a paralysed state.. Eg hearing what's going on, needing the loo, hearing (or not hearing more frequently) loud noises that would wake the dead but being physically unable to move or get up? Eg, I hear my husband call my name all the time but it's like I can't move or anything, I've always hated sleeping too long during the night because it only ever makes my headaches worse. I have ongoing bladder issues and even needing the loo so badly during the night doesn't let me wake up! I seem to think it's part of my dream and it's like my body is sort of tricking me into thinking it's all in my head! We have an old style alarm clock (two bells on either side with a small hammer in between that makes noise that should wake the dead!) but I DONT EVEN HEAR It! Tried what feels like everything but I can not seem to convince my brain to cooperate, has anyone had this happen to them and found out something that helps them wake up? Tried vitamins, relaxation, early nights, not sleeping and just napping every now and again, now at a loss and quite baffled... I'd like to get up in time for a pee again and hear my lovely alarm! Thanks
