It's a common theme associated with SSILD. It's a form of awakening that borders on real awakening. Under this situation, you do receive input from the physical world and if you move physically the transition is seamless, just as if you'd truly awoken. Interestingly, this is also a state which you can seamlessly turn into an OBE. The best way to accomplish this is as follows:

1. Relax your head and allows it to sink into the pillow. You can even apply some pressure to help it sink further.

2. Focus on your hearing.

3. Gently raise your hand without pulling your muscle. This may sound weird but it's actually quite doable in that state.

4. Reach for and grab your nose to do a nose-pinching RC.

5. If RC succeeds, roll toward your hand as if you are pulling yourself out of bed. This will result in an OBE.
