Does anybody else experience this?
When youre fast asleep and then you suddenly feel like youre falling and wake up and feel a bit surprised.

Answer

this is called SLEEP STARTSbrbr Clinical manifestationsbrbr A sleep start typically consists of a whole body myoclonic jerk that is produced by contraction of skeletal muscles. The main muscles involved are the axial ones, but contractions may also affect only or limbs or parts thereof. Sleep starts are often accompanied by a vivid dream, by the subjective impression of falling, or by some other sensation. Pure sensory phenomena in the absence of a body jerk socalled sensory sleep starts can also occur Sander et al . An utterance sometimes accompanies the sleep start. Sleep starts may be noticed only by a bed partner and not by the individual. When excessive in the degree of motor activity or frequency, sleep starts cause awakenings, and repetitive episodes can produce sleep onset difficulty. In extreme cases, tongue biting mimicking an epileptic seizure may occur Kimura et al .
