I can do this on multiple occasions. A few times going to sleep, once this morning attemting to DEILD.

On both occasions I lay still for 40 minutes or so, by not my hands/feet are completely numb, or tingly. I see shapes, but I can still move if I want. Basically, I can't get any farther... Is it I can't fall asleep? None of these were with WBTB however.

The DEILD was from a normal dream if it matters. (But I did get these sensations much faster!) And the DEILD I only tried for about 20 minutes. Should I focus more on imagery? Am I not trying long enough? Should I make more of an effort to use WBTB?
