Probably the most basic offering I have for you is to remember to remain calm and treat control and dream actions as if it's completely natural. You need not try too hard for control. You just do it and cast all doubt aside. Remember that anything is possible within a dream and let that reassurance translate into greater control.

Some people wake up because they struggle to focus, often because of doubts or lack of confidence. Forcing it is counter-productive. Becoming too emotionally involved works against you as well. Remain calm if possible.

I don't know if I helped at all but those are some general things to keep in mind.

And finally, welcome to the forum.
