eLucid has a good point, I mean yes people do normally have several dreams per night but if you don't get enough sleep to enter REM sleep then you might not have any dreams within the time you slept, because you don't always have dreams in deep sleep so it is possible not to dream sometimes rather than it being you just don't remember it.
