I have just started trying to lucid dream. I am trying the WILD technique and counting down after relaxing my body. I can get to a semi dreamlike state where I have dreams and I feel like I am on the verge of sleep, but then my body shortly after entering that state will flinch and I will come back to consciousness. Often I am not aware of the flinch, but my partner near me will tell me of it, sometimes I am, but it stops the dream experience and I wake up.
I can recall often having this problem for years when trying to get to sleep normally, before ever trying lucid dreaming. Sometimes it is minor, like just my hand flinching and sometimes my whole body doing a spasm. Often I think it is in response to what is happening in the dream but not always.
Any ideas as to what it is caused by and how to stop it?
Thanks for your replies.
