weird eye things

what’s up I died but I came back. anybody else see this junk?

I swear sometimes I'll just be hanging out or whatever and out of no where I get these shadows in my vision. It's like black blobs in random places of my vision, they're not any specific shape and they fade away after a while but they're annoying.  I've also been seeing some freaky people, I see double of the same person. I'll be walking and see someone pass in front of me only to turn and see they're somewhere else. I probably need help but I'm thugging it out for now
