OK so I had a dream about my ex and at first he wanted
To be wit me then the next minute he was basically floating in
The air too get away from me what does this mean?

Since he is an "EX", he must have initially wanted to be with you but now has "floated away". This dream occurred only in your mind & does not involve him physically or spiritually. Your subconscious mind was replaying the event in dream world time. Forget him & progress in your life.
