Sandy Hook survivor’s hell again

Some students who survived previous massacres at Sandy Hook Elementary School or Oxford HS were faced with the terror of gun violence yet again during Michigan State University’s rampage.

Their terrified tales of déjà vu surfaced as another survivor of the MSU attack said the killer didn’t utter a word when he shot up her classroom — and that heroic students put their lives on the line to save others.

“I am 21 years old, and this is the second mass shooting that I have now lived through,” a stricken Jackie Matthews (right) said Tuesday in an emotional TikTok video.

Currently a senior at MSU — where a gunman killed three people and wounded five others Monday night — Matthews was a student at Sandy Hook in Newtown, Conn., when Adam Lanza slaughtered 20 students and six teachers and staff on Dec. 14, 2012.

Calling it “incomprehensible’’ that she had to go through a second school shooting, Matthews said she still suffers from a “full-blown PTSD fracture” in her lower back from the hours spent crouching in her classroom to evade Lanza’s unspeakable rampage.

“My heart goes out to all the families and the friends of the Michigan State shooting,” she said. “But we can no longer just provide love and prayers. It needs to be legislation, it needs to be action.”

Other MSU students who survived Monday’s attack dodged teenage maniac Ethan Crumbley during his assault at in Oxford, Mich., about an hour and an a half from the university, in 2021.

“Tonight, I am sitting under my desk at Michigan State University, once again texting everyone ‘I love you,’ ” tweeted Emma Riddle, a former Oxford student, around 12:30 a.m. Tuesday.

“When will this end?” MSU student Claire Papoulias told the “Today” show that she was in her evening history class with about 20 students when she suddenly heard “three or four gunshots directly behind my head.

“I dropped to the floor with all my classmates, and someone was yelling that there was a shooter,” she said.

“At that moment, I thought I was gonna die. I was so scared.”

Papoulias said killer Anthony Dwayne McRae, 43, then “came through the back and just started attacking people.

“I will never forget the screams of my classmates,” she said. “They were like screaming in pain for help.”
