Dreaming of your dad means you need guidance through some troubled times. You will need someone to hold your hands when encountering these troubles. It could be big, or it could be small, the important thing is the have someone guide you through this one time before you are able to tackle it yourself going forward without any hand holding.
Your dad in dreams also signifies that the time is ripe for you to start thinking about fatherhood, and starting a family of your own.
