How to increase my awareness?

This might sound strange, but I have issues with my overall awareness. I daydream a lot, I can't focus, I don't have ADD/ADHD or anything like that. I know it's more of a temporary state of mind than a long-standing disorder. I'll be talking to someone and then realize that they've finished talking and have no clue what they just said. Also, I'm very indecisive and I can't make clear conscious decisions.

Another issue: I'm emotionally numb. I read an article about low awareness and it said to ask yourself how you honestly feel. I feel nothing. Almost all the time.

Anyone know anything about this or what I can do to improve on this? Any help is much appreciated, thanks!
