Does anybody know such dreams?

You hear the phone ringing and you actually wake up from this. Then go to check the phone to see who was calling and realise that it didn't even ring?
Or you hear your alarm clock going off and you wake up, turn it off, go to the bathroom and get ready for the day. Then you check the alarm clock again and it is actually one hour before you had to get up?

I have them sometimes, and it is a bit freaky as my mind seems to play tricks on me and they seem so realistic.


Anyone out there who has experienced similar things or am I the only one?
