weird dream! did i hear my guardian angels voice?

in this dream i "woke up" and it felt realllll so i grabbed my ipad in this dream so i could check the time and the time said 3:30 p.m. and i was like oh no i woke up late and i started panicking and than i heard a voice say "you need to wake up right now!" andi woke up  so i checked the time in real life and in real life it was 9 a.m. so i looked up the dream and supposedly your not supposed to check the time in dreams for some reason...
