I don't have this problem but in a dream I had a day ago I got a low level of lucidy twice..xD...I was like in the dream..."Oh, I must be dreaming" Without any dream sign (Cause I don't have one yet as my dreams are very random) I guess I just felt it..xD...Then later in the dream it happened again..I had a low level of lucidy for a second and I realized I must be dreaming...then did nothing about it and continued on with teh dream..xD..My problem is getting a high enough level of lucidy to do something about the fact that I'm dreaming..
