I have a hard time with missions like the one with the Terrormorph at the food processing facility. Jump scares and being chased just freak me the fuck out. And of course I started this quest line at night, thinking "Oh, it's a first mission for the Vanguard, I just need to fix some comms, maybe fight off some pirates at most, and then I'll go to bed" and then end up in Space Jurassic Park. And that proximity sensor only made it worse, with the "beep beep beep" while I'm trying to figure out where I need to go next without getting ripped to shreds. (I've seen this movie--I'm gonna die!) So I'm hiding in the first building with the breaker, and I make sure to shut the door because "beep beep beep" is getting faster, and as I'm moving across the room in a crouch (I didn't know if it could see me through the big window, and there's a hole in the roof in the next room), for some unknown reason dumbass Sam goes back over to the door (the opposite direction I'm moving) and opens it again. And I'm yelling "Dude, what the fuck are you doing? You fucking dumbass!" as I'm trying to hurry back over to close the door again before we get found and eaten. If companions could die, I would have fed him to the Terrormorph.
Thankfully, I didn't get around to the Vanguard missions until I was level 15, so I had a helmet with Chameleon that made me invisible in crouch when not moving, plus a gun that literally kills things with fire. I managed to get some of the turrets turned on and they helped me take out the nightmare fuel pretty fast. Then I stayed up another couple hours to work on my ship and outpost to calm down enough to go to sleep.
