newborn crying spell

J

My 5 week old doesn’t cry much at all unless she’s hungry or wants her paci and it falls out. I just took a super quick shower with her in the bassinet by the door and she started crying cause her paci fell out of her mouth, I continued showering for like 2 mins and when I got out she was high pitch crying so I went and picked her up and she was bright red and sweaty and then instantly passed out. she was still breathing but was knocked out and woke up a minute later to cry again but stopped and is fine now but i’ve never seen this before??
