OK,i'll make this short and sweet,last night april 19,20th? i woke up at 4:30 a.m. (i think)

I did a RC by looking at my clock,it said 5:05,i looked back again then it said 4:31,and i didn't pay much attention to it and at this point i was to tired to care what the time really was when :

I lie back down to go to sleep and i heard a buzzing noise,it kept me up untill 5:01 (i think)

Can someone tell me if this is a beggining of an OBE?

Thanks
