Help for re occuring break in dreams in morning

My home was broken into whilst I was there and it was really horrific hearing what I did. A few weeks ago my dad accidentally set of the alarm at 2:30am and I feel like the strong, scared feeling has come back. I always feel a but vulnerable for my safety after the robbery but it was never interfering with my life. I tried therapy but back then I couldn’t take it seriously at all because I just thought it was a ‘soft thing for softies’. I know, not helpful.

But now at nights, after the accidental setting off of the alarm, I usually wake up at about 4:30am as my lovely dream turns into my nightmarish thoughts of someone aggressively breaking in. When I wake up and this happens, my heart beats faster and I feel really alert and scared. A bird may tweet as it is so early in the morning and my heart may get scared again and beat fast- thinking it is someone trying to break in. Also I don’t know if it related but when I wake up in the morning I have a really strong urge to wee that sometimes, this happens randomly, I cannot hold it and wet the floor completely like a toddler- so embarrassing.

What can I do to change this as it has been 5 years since the break in and I clearly need to fix this?

I’ve tried hypnotherapy and thats a waste of time, wish it worked for me though. I’ve also tried normal therapy but like I said I didn’t take it seriously. Do I even need help? And what is it that I’m experiencing?
