So my friend is acting weird about shifting..

So for context I have a friend who is a shifter and we talked about shifting a lot, like a TON, but something started happening lately, two days ago I was on tiktok and saw a shifting video I of course showed it to my friend but he said he doesn't know what shifting is, I thought he was messing with me and so we left the topic. The next day I invite my friend over for a sleep over and like the same as the last time, I saw a shifting video but when I showed it to them they said they have no idea what shifting is, I told them to stop messing with me but he didn't have a clue.. I asked him about other conversations and I even opened the lifa app on his phone and he simply said he doesn't remember anything..

Is my friend fucking with me or did I like shift to a reality where my friend doesn't know shifting..I have no idea..

PLEASE HELP
