Can astral projection have anything to do with severaly interupted sleep?

I have been studying up om astral projection and cant seem to do it but i did read in one of my finds that you astral project especialy in your sleep thats what happens when you dream in color.ihave been waking up at least 10 times a night and i never seem to be asleep just kinda on the brink of conciousness and unconciuosness.i wake up suddenly at all huors of the night i also read thats a sighn of sleep astral projecting but it is getting bothersome and a bit scary especially since i dreamed i murdered this guy last night which was very colorful and very vivid.does anyone have any advice or suggestions on this matter?This has just started happening since ive been interested in this.
