Vanishing twin syndrome was first recognized in 1945. Vanishing twin syndrome is when one of a set of twin/multiple fetuses disappears in the uterus during pregnancy. This is the result of a miscarriage of one twin/multiple. The fetal tissue is absorbed by the other twin/multiple, placenta or the mother. This gives the appearance of a "vanishing twin." http://www.americanpregnancy.org/multiples/vanishingtwin.html
Usually one, occasionally two although twin pregnancies generally abort before birth or one foal is dead at birth or dies shortly after birth. Often both twins die. Successful twins are rare. Most breeders use techniques to prevent twin pregnancies.

This is a psychological question rather than a pregnancy one. My husband is an identical twin, and we have fraternal twin son/daughter. when asked what it is like being a twin they can't say, any more than I can say what it is like to be a singleton. Elvis Presley was a twin, his twin died at birth.
Marlon had a twin brother named Brandon who died at birth,
