I understand about being afraid of someone strange being in your house, especially at night. I don't have that fear now but did when I was young. I lock up well at night and have been firmly assured that burglars target houses that are empty, ie people at work.
Apart from what has been mentioned (& the childrens' things is most scary, I can still imagine scenarios even though mine are grown), I fear my husband dying suddenly. You know, I get a 'phone call telling me he's had a stroke or heart attack and by the time I get to hospital, he's dead.
For myself, I fear being paralysed and helpless, at the mercy of others.
I am also afraid of car accidents (I don't mean a bump but a serious one like you see on Cas);
also worry about husband maybe being paralysed and helpless, my instinct is to look after him but he is very big and constantly trying to work on his weight;
falling off a high building, can't bear to read about that or see it on TV;
burning (like Grenfell);
sometimes drowning, I can swim (though haven't swam for ages) but panic easily.
Plenty of other things at different times.
I get panic attacks which I have learned to manage but occasionally have some which actually wake me up in terror. Not nice.
Apart from that I'm OK :-).
It helps to write it down. I hope it does for you and I sincerely hope I haven't intruded my issues onto you, that wasn't the intention.
