So basically I've been trying to find my dream sign for the past few months to strengthen my ability to realize I'm dreaming.
I haven't found it yet, and i just had a few questions...

Are dream signs consistent? For example, maybe your dream sign is teeth falling out. Does your teeth fall out in every dream, or just most dreams?

Can a mantra help me find my dream sign? If I were to repeat "I will notice my dream sign" or something along those lines, would it help in any way? (I would also appreciate any mantra suggestions )

Can people have multiple dream signs?

That's pretty much it..... Thanks for everything and happy dreaming!
