Had a sex Dream FELT so real.... but i'm a virgin?

Last night I had a dream that I was having sex with the guy and I could actually feel him penetrating me. Like I felt a pressure on my Lower stomach. I remember I even told him to slow down because it was a little uncomfortable. Is it possible that that's how sex feels? I mean I'm a virgin how could I fel the actual penetration in a dream, if i've never felt that before?
