You missed out on the tomb raider demo disc that came with PlayStation magazine (probably issue 73 based on the fact I have it and I wasn’t subscribed very long while demo discs were a thing) Same era.
If you went for a swim in the pool, and swam into the side, you’d not only get a constant intense vibration, you’d also get to see her swimming motion, and I don’t think it had breath mechanics yet (or at least she wouldn’t die in the demo zone), so you could take your time. Win win.
There was also a vibration test in the menu if you just wanted no frills.
