As Perry pointed out, there are 5 stages of sleep that occur in cycles through the night, averaging about 90 minutes per cycle.
In the early cyles, it is typical to have more stage 1 & 2, and less of the later stages; and later in the night you would typically have less of the early stages and more REM.
REM sleep is a period during which the body is extremely relaxed. More so than during other sleep stages. Typically more severe sleep disturbances occur during REM sleep, and there are times when these disturbances are missed during titration as sovann noted. Consequently you still have apneas during REM that wake you up, but not during other time periods.
The weird dreams are an indication of what is called REM rebound, and is an indication of improvement. It has to do with having gotten poor REM sleep for a long period, and now you are experiencing an improvement. When your sleep debt is paid off you will go back to normal dreams, whatever that may be.
Of course these are guesses on my part, but a call to your sleep doc would be in order. If I, and the others, are right, he may want to increase your pressure a little.
