Have you ever had those dreams where you're in the middle of falling asleep and start to dream. One of those dreams that, if you were to trip on the kerb, would make you jolt and wake up? 
I'm sure you know what I mean, and a lot of people probably have them, if not most.

I get them extremely often but I also get more 'sinister' wake-ups.
Sinister isn't the right word, more of a realisation that I'm asleep, like a lucid dream but instead of it feeling good and being in control, my subconcious takes over and I end up feeling like I can't move and I'm trapped.
I'll "kind of" wake up at this point and be fully aware of the dream. My eyes are open but I can't move or say anything, it's like something's holding me back from breaking free of that grip! Then I burst through, finally and I'm in a conscious state.

It frightens me somewhat because I've noticed over a long number of years I've become more "aware" of that barrier between the conscious and subconscious. Like something you can reach out and touch. It feels now like it's breaking down. Like it's weaker somewhat and that it's not too long before there is no barrer there at all.

What's extremely weird, which, again I've had a few times is that, after this happens if I'm drifting back to sleep I'll be thinking of it and it's like my subconscious tentatively prods away to draw me in and I'm still aware of it then I get what I can only describe as an attack on the barrier. Like something hits this barrier with some force. What's worse is I get about a half-second delay before it happens, a kinda warning that it's about to then it does but I can't do anything about it!

What would happen if that barrier broke? Am I being irational thinking like this?
I don't know!
Does or has anyone experienced this? What could it be in honesty? that's the question!
