Condoms breaking...

I'm 16 And I've dated my boyfriend for a year, but he recently had a dream that a condom had a pin hole and I was pregnant.... But I don't believe it. Thought just a silly dream.. But his dreams tend to come true.... And now he thinks I'm pregnant... But I can't be... My parents are so strict... I'm so scared of what they'll say and/or do if they found out... Any advice from anyone.. Please help. Any input would help a bunch...
