Watched "Sanctum" the other night,

I got it from Netflix months ago when it came out and couldn't really finish it. Just not good, IMO. Maybe I need to give it another shot.

I didn't feel claustrophobic, but like I said, I found myself holding my breath.

However, it was not because I was scared, it's was when a character was underwater without oxygen for whatever reason (no spoilers). When they were holding their breath, so was I.

What was funny to me is I overtly noticed I was doing it. I even rewound certain scenes and I would again hold my breath when I watched the scene a second time. Hell, I'm doing it right now just thinking about it.
