Ok, so I'm new to the forum and LD and everything. I've been reading some threads and i notice people talk about vibrations a lot. What are they?? I THINK I know what everyone is talking about, but I'm not really sure. Because last night I was attempting to WILD And I think I was almost there when I felt everything shake like I had jerked or something, and that woke me up. I know sometimes we jerk in our sleep and I was just wondering if thats what everyone is talking about or what??
