Lana had a terrible concussion and was unconscious for a while.
After she woke up she described Clark her dream that reflects
what exactly happened to their friend Chloe.
Clark: Do you want me to call her dad and ask him if she's okay?
Lana: You know,
I'm sure it's just the concussion. From the concussion?
I"m sure it (this weird feeling/the dreams) is just (the results of having) the concussion.
Thanks, Barbara!
