For a while now I've been having dreams in which my teeth fall out but they happened sporadically.

In these dreams I am subject to an EXTREME amount of pain.

In every dream I start to feel my teeth with my tongue. I put pressure on the backs of my teeth and I feel a crack and they move in the gum I then try to push them back in place but they crack even harder. This part is the same in every dream

Here's where they vary

In some I keep trying to put them back in place and they just bust and I spit them out (lots of blood)

in others I decide to deliberately pull or push them out (this is extremely painful) (also lots of blood)

in some I try and stop myself from tonguing them but I can't resist the urge and I keep tonguing them until they fall out. (still lot's of blood)

Lately I have been having one of these dreams EVERY SINGLE NIGHT

Last night was the most horrifying.

I played with my upper from teeth and they cracked hard to the point that I knew I couldn't put them back in place so I pushed them and spit them out.
All of my front teeth came out of my mouth with mouthfuls of blood. I saw and felt a whole pile of teeth come out and land on the sink. thoughts raced through my head about things like "ill have to get fake teeth or dentures.
I turned to look at my friend and he jumped back with a horrifies look on his face.

I have been told by several people that I must be grinding my teeth at night.

The reason for my dreams is not my number one concern. I would simply like to know a few things and I'm hoping you can help.

1. What can I do to make them stop?

2. Is it a good idea to try use this as a dream sign for lucid dreaming?

3. Is it a good idea to make this my reality check? I.E. pushing on my teeth or wiggling them with a finger to see if they crack? I suppose I would like to know if this will just be painful and distract me.

4. Why am I having this dream every night?
