I believe i was abducted last week?

I am 16 and live in London. I live a normal life. party a lot. do a lot of sport. mentally and physically well. Last week at about 2 pm i woke up screaming and levitating over what i believe was my bed. it was really bright and there was weird noises. I didn't believe in aliens but now i don't know and if i was and they do exist there is a chance of them coming back . if anyone can think of any other explanations or reassure me in any way it would help so much
