The classic interpretation of a dream about falling is that you are falling for someone, your emotions are tumbling out of control and you are struggling to hold on. Think about how you are experiencing the fall, are you enjoying the sense of danger and the journey or do you feel like you were pushed and are worried about hitting the ground?
Your feelings about the fall will represent your feelings about a possible new relationship with someone you are close too. If you are falling into water, this means the feelings are about someone who you would not normally fall for. Think about whether you can enjoy the swim back to shore or whether you are scared about drowning.
If you are worried about going under the water this shows that you are trying to reject the emotions you are feeling so you just need to be strong and face up to what you really want.
When you are scared of falling in your dream this represents a situation in your waking life where you are feeling anxious and stressed and you are not sure how to handle the situation. The dream is reflecting how you feel about the situation and some emotions that you have been trying to repress are inadvertently being released.
If you have fallen off a cliff this shows that you are struggling to find out how you really are and you need to think deeply about who you are and why you do the things you do.
