NO you cant.
Coma is a pathologycal (non-normal) state of the brain functions, that do not have the components of normal sleep
In normal sleep we have normally, what we call "four stages" that are defined by very clear cut "sleeping waves".
When we reach phase III, we start involuntarily moving our eyeballs, and we reach the maximum muccle relaxation, (the so called REM or Rapid Eye Movements). and in THIS period of REM, we do dream.... (you can see at times,people who are asleep, actually moving the eyeballs, as if " they were pursuing a moving object")
In coma, there is no sleep wave pattern, nor REM stage, and thus, there are no dreams by definition, and the electrical waves taken to comatose persons, do not show the typical IV phases of NORMAL sleep.
As you can see, dreaming ina coma, is utterly impossible, otherwise, it wouldnt be a coma
