Well it looks to me like the man was helping you, so you have friends. He probably needs help as much as you but don't bother worrying. Sometimes we wander into bad places in our dreams, and this is a bit like Aragog's lair. The 3 mirrors to me represent past present and future being rolled into one, revelations. That isn't a nice thing to end up knowing about. The warehouses and maze to me represent our homes, the streets. Your key means you can be easily hacked, picked off like a baby cow straying from the herd. You are attempting to go it alone, but shouldn't. You need friends, anchors in spirit, good ones.
I had these dreams too. Best thing is to raise your vibration. Shake it off and maybe even move house. Get off grid more if you can, lose these people. Forget the number, you're a person, not a pig. They want you to think these things make you special. Whatever you believe can be used to hurt you. So, don't give the bad dreams power. Don't think you inparticular are in trouble, that whole mindset again gives them power which you are being encouraged to learn how to not keep giving away so easily. It can be an invitation to study deep mysteries which is advanced. Virtue signalling or not being popular are easy ways to get trapped because they are scornful people. Shake
Ask for a sweet gypsy spirit or a happy pirate to show you a nice dream. Maybe a biker can give you a ride
If you're in a bad spot wolves will guide you home. Better there was a wolf on the chain than a key. That indicates a puzzle, a gauntlet to run, bad business, introversion. Labyrinths, the crystal maze etc- it isn't easy. If it were Harry Potter it'd be Slytherin, and people rarely want it like they think they do. Maybe create a spell where you ask for a guide to help you home at night, and tie a new 'chain' like a cord onto your wrist. Wolves are your friends!x
