Hi! Could you interpret these dreams for me?

First one is a recurring dream that has the same basic form even though the settings are different each time. Basically, I'm always on a journey accompanied by some people around my age (20s) who I don't know. A few times it's been in a coastal town that I've never been to. There is a rocky island across the water. (Sometimes I try to swim there but almost wake up as the waves get too turbulent). I usually have to get to the church via the graveyard and eventually enter it and begin to search for a hidden relic, sometimes I find it under a floor tile or inside a book. Every single time, I wake up just as I find the item, so I never actually find out what it is. I only remember actually seeing it once: it was a black box with an inscription on it in an alphabet that looked like series of X's and O's. Variations on this include times when I'm running through immense castles or cities in search of this item. Once I was in Egypt rummaging around subterranean tombs. One of these tombs was painted in bright colours with rivers of liquid streaming around. This bearded man (who I couldn't see) was threatening me for entering the tomb. His voice echoed around the place.

The second dream is as follows (I've had it 4 or 5 times): I'm in a North African town around the end of the 19th century and there are French soldiers everywhere (I know nothing about this period in history). I'm running away from them because I'm due for execution by firing squad down by the shore, along with several other men. So I'm running through the old buildings and knocking on the doors for refuge. The cool thing about this dream is that my visual memory of it is so clear I could even draw the interiors of the rooms in ran through, and the intense colours, the reds and browns, and the old woman whose kitchen I ran through as she was cooking. Sometimes, this dream becomes very strange: parts of the city break off into separate "islands" and other buildings appear. I explore this strange place and there are buildings from different architectural eras and places, like colossal Roman temples and Renaissance buildings, but within walking distance of each other. Once, parts of Venice were there too. (I've never been to these places in real life).

The third dream (very frequent): I'm in a huge, seemingly interminable old graveyard. To begin with, there are people there too, who I don't know but are friendly. Everywhere I turn are more graves and mausoleums, it's impossible to escape them. Then at some point the people disappear and I'm left alone. I'm terrified but I never see any threat. Then night falls and I'm forced to sit by a grave and light a lantern. Luckily there is a presence, a woman, who I intuitively feel will comfort me even though I can't see her. Then I wake up.
