Space Cruise through Hell

You won a trip for a Space Cruise to a paradise planet. As you ready to sleep through the 7 hour space jump through the gateway, you feel odd lights dance over your closed eyes. Looking out the window reveals a terrifying picture. The gateway is engulfed by a large portal that looks more like a tear in reality. You suddenly wake up in your cruise cabin sweaty and startled. Checking the window reveals the paradise planet in sight, but something feels off. Which dimension did your space cruise pass through? Inspired by Event Horizon and Fifth Element.
