Lucid Dream

Ok, so, what does 690452 mean? According to TikTok, if you write the numbers 690452 on your wrist before you go to sleep, you’ll be stuck in your dream or a parallel universe forever. That means if you die in your sleep, well, you're dead in real-life too…

But what is the significance of 690452? Um, no one actually knows. However, according to Urban Dictionary this particular sequence is a "cursed" number or the "hell or heaven number".

Shockingly, some TikTok users have reported that it hasn't worked for them while others have warned against participating in the trend because there's apparently a 50/50 chance of survival or getting stuck in another universe.

Anyway, that hasn't stopped people hopping on the trend and attempting to see for themselves.
