Finding this post is one of those OMG moments for me!!!! I used to suffer from these dreams sooooo badly! This is validating and exciting because I conquered these terrifying nightmares and hopefully what I learned might help someone else who needs to make them stop!!
First, I want to explain what mine were like so you can decide if my case is similar enough to warrant taking any advice from me, okay?
Usually (tho not always) these dreams occurred in the same dream-like state as the "falling dream" that more people have experienced and can relate to ... very "semi-conscious" dream which is why it seems so very real and vivid. In my opinion, this is when the sub-conscious will push a matter of utmost importance into the conscious mind ... something which NEEDS to be dealt with. You will likely keep getting this dream repetitiously until you at least begin dealing with what your subconscious is begging you to, if your at all like me.
In my dreams I was swallowing lego pieces, earrings, necklaces, puzzle pieces, bobby-pins, open safety pins and needles ... often even larger things like a sock or a facecloth! (my gag reflex is working overtime right now while sharing this). It was SO vividly real ... the physical sensation ... that I would jump to the bathroom and stick my fingers down my throat trying to bring up what I feared was falling towards, or already in my stomach! I know that sometimes I was gasping for air ... but most times found I could breathe through my nose? So, while at first I thought it might be sleep apnea, this alerted me to thinking that it was something else. Yet, I still had no clue what.
One dream in particular ... I was swallowing yet another necklace. I managed to stick out my tongue quick enough to catch the very last length of it with my upper-front teeth and pin it to my tongue (I hope that makes sense. Very tricky to describe). I reached in with my fingers and found nothing there of course ... but I had scraped my tongue hard enough to make it bleed. It was while swallowing the trickle of blood that the meaning of the dream popped into my thick skull!
*** What are you trying to swallow in your life that you don't want to swallow?***
***If it is hard to swallow, it probably isn't good for you!***
This dream is showing you that the anxiety in your subconscious is SO high that it needs lowering ... what is it in your waking life that is bringing you the most anxiety? Is somebody else pressuring you to take on more than you can bear? Are you pressuring yourself to do something that goes against what you REALLY want to do?
Try to figure it out BEFORE you bite your own tongue ... that really hurt like a SOB! :p
Once I figured out the meaning and began working on some sources of anxiety the dreams subsided and eventually stopped. Don't get me wrong, I still had nightmares ... just no more of these ones, thankfully!
I hope this helps somebody.
