Can anyone help me with a dream i had ?

The other night i was in a deep sleep and in the dream something felt like it was holding me back a very strong force holding me down and all over my body there was this very sharp tingling feeling and as i tried to wake up the pulling and tugging got stronger and i was shouting "let me go let me go!" and the pulling and tugging at me was so strong in the dream it was very hard for me to speak by the last time i yelled it was aloud and then i woke up and the tingling all over went away within the next 5 seconds. Anyone know about this? dreams? Astral projection maybe or even Ghosts? Thank you for your help and advice. ^_~
