I Had Suppository For The First Time In My Life

I had suppository for the first time in my life recently while in hospital. The problem is....it's been a week since and whenever I go to sleep I always feel like there's one in and I'm about to poop while I sleep. It happens every night. I rush to the toilet and nothing. Sometimes I actually get the sensation or feeling that I have actually soiled myself during the night and I haven't. Is this common? Is it psychological?
