It was a bad trip because the fractal nature of time implies that your life repeats itself infinitely many times (probably with the exact same details). You can never rest, it's all an infinite loop, and that idea made me extremely distressed, like this fractal nature was some sort of punishment or permanent purgatory.
This echoes Nietzsche's idea of the Eternal Recurrence of the Same, which he thought would in fact be terrifying to the ordinary man, but the overman could live their life in such a way that the infinite repetition would be fully and unreservedly welcome.
But it's the strange-seeing that's the real feast.
