Seizures while sleeping? How can I tell if Im having them?

Im 18 years old. I was diagnosed with Epilepsy about 2-3 months ago. I have currently had 4 seizures, all of which were awake. Recently I've noticed that when I wake up Im more tired than usual even with the 4-6 hrs of sleep i get. My blankets are throw around, one ends up on the floor completely which has never happened before. I am sometimes in a totally different position, once I awoke and went to turn my body left to get out of bed only to feel my desk after i turned my body left, my desk is at the foot of my bed. I also keep a set of Ipod speakers on my night stand on the left of my bed. On the stand is a lamp, alarm clock, phone and the speakers. Recently the speakers and only the speakers have ended up on the floor. The speakers are the second farthest thing away on the stand when Im in bed. I suspect that Im having seizures while I sleep but how can i be sure. Please Help me.
