So many "I'm Sorry"s. While you do have my condolences, I don't think that's what you posted for Let's look at the dream...

First, between the hallucinations and the sleep paralysis, AND the description of the pain of being shot/stabbed... I recommend you get yourself to a sleep clinic for testing. It sounds like you might have some sort of issue similar to sleep apnea. :: I am not a doctor, and make no official diagnosis :: But still, get yourself checked out. This at the very least will rule out something more concerning.

Sleep paralysis is fairly common, especially in vivid nightmares. It's basically your body being stuck between waking up and being in REM sleep. The hallucinations may also connect to this, as the REM effects may linger as the waking mind regains control...

Now, as for the imagery... Every character in your dream is you. Not just the daughter, but ALL of them. Even the intruder.

So you and the daughter and this disabled man are celebrating. There is a displacement between you and the daughter, though you describe her as nice. Do you see yourself in a bad light? Something to consider. Then you touch the man in the wheelchair. -I'm going to tangent for a moment- Did you ever have a hand or a foot fall asleep, and then when you start to regain feeling again what does it feel like? Pins and needles???? So you touch the man, and -you- feel the pins and needles. But when you started you said he could only move his arms, and now he's saying he can feel one leg. Your connection to him is healing. This is a standard Jungian interaction - and an ideal one! Now before I get too much more into this connection, I have to address a dynamic here. This man is a father. You have become his daughter. But perhaps you made yourself separate from the situation being addressed? How do you feel about -you- dad? If I had to wager a guess, presuming the wheelchair man is an image of your father, I'd say he is closed off and emotionally distant - not allowing any real chance for you to connect with him, But now here you are, connecting with the father figure! And you have become the daughter! And you are feeling something coming from him, and he can feel his leg. He may not be able to use it, but it's there, and knowing that the feeling is there is quite important.

But as things look up, a shadow self (the part of you that you dislike) comes up through the fence. It's only when this danger presents itself, though, that you realize you are the daughter. There is no real build up or epiphany, and you say being shot or stabbed in the chest has happened in dreams before. I think this more connects with the statement of pain on waking. Especially considering that you show signs that your sleeping and waking mind don't entirely disconnect on waking. I would suggest you look into what is giving you the feeling of emptiness. Is it the disconnect with your self as a daughter? This could be part of the issue since you only realize who you are when faced with the problem. It may also have to do with if you find yourself lacking connection with others, as you are also the man in the wheelchair - feeling nothing. In fact, that connects with the statement of feeling empty.

Bottom line, consider how you relate to your dad. Then consider how and why you feel yourself as numb. Remember to embrace these parts of yourself, as connecting with them can allow you to heal the numbness just as is shown in the dream. Finally, ask yourself why you feel so empty...what is missing? This seems to be a cause of some deeper-seeded pain. And get checked out at a sleep clinic, at least to rule out something like sleep apnea.
