Recurrent and persistent bad dreams

I seem to have recurring, persistent dreams that profoundly upset me.

There are three main themes. 1) The first typically occurs in a dream of being somewhere other than a place I am familiar with. In this dream I am usually among a small group of friends or acquaintances; our agenda is (ostensibly) to find our way to some other venue or destination (sometimes home), but either suddenly or slowly the 'others' with me go separate ways or disappear, leaving me all by myself in a strange place, trying to find out where they went.

2) The second one is a very, very old one of urgently needing to find a restroom to relieve myself, but searching in vain for one. If I do find one, it is typically either not working (out of service) or so horribly befouled with excrement that I can't possible use it.

3) The third recurrent dream finds me in a physical conflict with someone; I try to resist or fight back against them but find that the moment I do so, I become so weak that I am unable to break free and resist the aggressiveness of their attack.

These dreams result in my waking up late at night, not quite in a cold sweat but very, very agitated and frustrated. Last night, I had the restroom dream again and found one, but fell through the floor into a nightmarish 'cess pit'. An awful and quite disturbing, nightmarish scenario.

I am quite certain that these dreams are linked to early, childhood experiences and unresolved, childish dilemmas, but that's just my best guess , since my degree in psychiatry is from the 'ACEY-DEUCY, MIDNIGHT INSTITUTE OF PSYCHIATRY' (uncredentialed, LoL).

Any helpful insights into how to expiated these pesky 'demons?' FYI: I was an only child, lost my father at age 4 and was raised by a school-teacher mother to be a well-behaved, polite and considerate individual: all liabilities in our 'dog-eat-dog' modern age.
