Stop Being Light Sleeper How Can I Become A Light Sleeper?

How can I become a light sleeper? - stop being light sleeper

I sleep deeply and form of hatred. I set 2 alarms, both 2 minutes apart, and the volume is very high. But somehow sleep through it and could not remember them off. Thus, both are one or two minutes before it automatically. I always get in time for school or what I can do in spite of this, but I want to stop. For the "light sleeper" I mean, I do not want any noise in the house awake. Has anyone ideas how I do it? TY:)
