Recurring train theme?

Title acts as a tldr but here are some specifics

- in one dream I was at a station I know well, taking a journey I used to take every day, except the service board displayed a completely different journey to what I expected, and the train never came no matter how many people started filling the platform

- in another dream I was on a day out with friends and one pulled me aside and suddenly we were in this strange plain between a lot of parallel train tracks, with wires hanging above us. I don’t remember what we talked about- I know it was lighthearted in tone but a serious topic. Again, never actually saw a train, just the tracks.

- in another dream, I had to catch a train to catch a flight, and my family were already at the airport urging me to hurry up, but I couldn’t find my way to the platform as it was underground and I kept coming to new escalators and never actually getting to the platform.

- finally, I was on an actual train and as I walked through the carriages, people would just look at me. The whole dream was just that- going through each carriage, occasionally stopping by doors to look out the windows at whatever we were going past, and making eye contact with other passengers who were either sitting or doing the same as me. I didn’t recognise any of them.

Would love to know what people make of this as it’s been bugging me a little. I’m sure I have more examples as it’s been happening for a while now, these are just the ones that stick out to me.
