Lol I dreamed that I met an alien

[MetalHeader]

I dreamed that an alien landed on my balcony and I talked to him.
He was so nice and friendly and I’m still upset that he left :/
He said that he’s starting to get back pain because he doesn’t used to the gravity here on earth.
I asked him if he has feelings and he said that he hasn’t, even thought he apperead super friendly and intelligent.
He said that he is an super advanced AI, and that another aliens with feelings has depeloped him 7 billion lights years away from earth, but they can’t travel so far on space, so they’ve sent him to collect some data about the universe.
He said that he’s scheduled to get back in his planet in a few million years.
He also said that he can time travel..
I thought that he was going to stay a bit more but he seemed to be suffering from the atmosphere and gravity so I let him left
What do you think about aliens?
