Почему удаляются все элементы?

let times = 1000;
let timet = null;
function resetTi() {
    if (!timet) {
        let slee = {
            nosleep: window.t,
            usid:window.id,
        };
        websocket.send(JSON.stringify(slee));
    }
    clearTimeout(timet);
    timet = setTimeout(sleep, times);
}
function sleep() {
    timet = null;
    let slees = {
        sleep: window.t,
        usid:window.id,
    };
    websocket.send(JSON.stringify(slees));
}
document.addEventListener('mousemove', resetTi);

.....
if (y.nosleep == window.roomt){
    var elem = document.getElementById(y.usid);
    console.log(elem);
}
.....

.....
if (y.nosleep === window.roomt){
.....

console.log(y.nosleep);
console.log(window.roomt);
