Dream of No communication?

ok, i have had this dream about 2 times and in it, im in a bad situation, or someone abducted me but i have my cell phone. though when i try to use my cell phone i either: a) have no battery b)have no bars, or c) the call wont go through even though i dial it. like if i call 911 someone intercepts my call, or my phone refuses to dial it, or if i call my parents, the call wont go through. can you tell me wat this means???
