Keep Seeing The Number 21 Everywhere?

Everywhere I go I see the number 21. It's really starting to freak me out honestly. I've been seeing this number so many times everyday for the past year. The thing is, I don't even really think about it but it still shows up! If I look at numbers like the time, chances are I'm gonna see like 6:21 PM like the most recent time today. I see it on clocks, billboards, iPhone battery percent, video games, in the movies, (Example: in the movie "Click" when Adam Sandlers dad dies, his grave says 1971-2021) this list go on and on… My high score in Flappy Bird was even 21 for a few weeks! Also just recently I got into Blackjack at the Casino which is a game were you have to try getting closer to 21 than The dealer without going over. I see it so much guys, I'm not joking I must be going crazy lol. Do you have a explanation?

Because you're looking for it. See if 342 ever comes up. I bet it does if you constantly look for it

Everything's going to be okay.
You're in a safe environment.
You're hammered. You've had 11 shots of tequila.
It's your birthday!
Those signs are your decorations.
Happy 21st! You have 10 shots to go. Drink up.

Know what you mean. I'm not religious, don't know bible chapter and verse but one night I dreamt about Matthew 24:7. Looked it up and it means destruction of kingdoms. Spooky.

Like Bob said. You are looking for the number. When you wake up, the first thing you think of is 21, so the number on the clock will likely say 6:21PM. Think of 12, you will likely find the number 12 everywhere. Try to stop thinking of this.

I know what you mean. My answer is you are not alone. We
are behind the Eight Ball waiting for play. There's a song I keep
over-hearing, just before a life changing event, '… That's been the
ruin of many a poor boy. And, God, I know… I'm one…'
