Is this sound normal?

Hey. I have wondered what has happend to my guitar and playing lately. it's happening when i mute the strings. When i play in and out of muting my top E string rings out annoyingly (It's happening if i just lift my hand off the top strings even slightly). Especially when im standing up and playing... I don't think there is something wrong with my tecnique, cause i don't remember to have this problem previously.. could it be something with the guitar. It's happening especially when i play riffs on the low strings with palm muting involved..

Do you guys have some feedback on this? Could it maybe be the setting on the guitar?

I would check out this GT Channel episode on stopping string noise!
