Overview & Efficacy
Both the National Institutes and the American Academy of Sleep Medicine have both stated that biofeedback used in conjunction with relaxation training can help sleep problems.
This therapy is rated as probably efficacious (level 3 on a scale of 1 - 5 with 5 being the best).

Why biofeedback would help this problemSleep disturbances including abnormally long time to fall asleep, frequent awakenings at night long enough to be remembered, and early awakening without being able to fall back to sleep are frequently related to stress, anxiety, and depression. These problems and the extra worried thinking associated with them cause the body's normal "fight or flight" physical responses to interfere with sleep. Biofeedback used in conjunction with relaxation training and other behavioral approaches to controlling anxiety such as cognitive restructuring (which helps people rethink just how threatening the very real stresses they need to deal with really are) helps people recognize when they are having exaggerated physical stress responses and what they are responding to. The techniques help people learn to control the responses so they are not larger than they need to be nor last longer than they have to.
Brief summary of evidence supporting the efficacy of biofeedback for insomniaYucha and Gilbert (2004) state that in 1996, an NIH Technology Assessment Panel examined existing research and concluded that several non-pharmacological techniques, particularly relaxation and biofeedback, produce improvements in some aspects of sleep, but questioned whether the magnitude of the improvement in sleep onset and total sleep time were clinically significant. In 1998, the American Academy of Sleep Medicine recommended biofeedback along with progressive muscle relaxation for insomnia after reviewing the quality of research, using American Psychological Association research criteria. Biofeedback was rated "probably efficacious" along with sleep restriction and cognitive-behavioral therapy. (Morin et al., 1998) (Progressive muscle relaxation, stimulus control, and paradoxical intent were rated even higher.)

In sleep, the hippocampus and neocortex regions can communicate without interference from external stimuli. During the REM, dreams are made several times/night. The body is paralyzed during this time except for eye movement but the brain is at work dreaming. It's alert enough to external stimuli.
