Crazy Squirtle

I'm a piano student and I was working in my music theory book on the section about major scales. I know that a major scale is comprised of two Tetrachords and that a Tetrachord has a pattern of whole step, whole step, half step. I was reading about the G major scale which I know has an F# in the key signature. It said that if the F# was an F natural then the second Tetrachord of the scale would have a pattern of whole step, half step, whole step instead of whole step, whole step, half step. This makes sense but in the G major scale after the half step of B-C it goes C-D, D-E, E-F#, and F#-G. Wouldn't that make the pattern whole step, whole step, whole step, half step?

The other night, I had a dream with two black widow spiders. In the dream I was in my bedroom and my sister was there. When I saw the first black widow spider, I saw it outside through a window. I was telling my sister about it and then it was in the room with us. There was a hole below the window that it crawled through. That first black widow spider was huge, it looked like it was almost the size of a sofa cushion. Then I turned around to open the bedroom door and run away and there was a tiny one on the door handle. It wasn't right on the door handle where you put your hand, it was on that little slender part that connects the doorknob to the door. That one didn't even look like it was moving, It looked like I could've turned the doorknob without it doing anything. Anyway, since it was on the door and I was afraid of getting bitten, I turned around the large one was moving closer to me. I backed away but it was moving closer each time. Then I woke up out of fear. Then last night I had a dream about an actual black widow. A woman who killed her husband. I don't mean to gross anyone out but she was eating the body! I've looked it up and it says that dreaming of a black widow means there could be someone, possibly a woman in your life who is manipulating you/insecurities in a relationship with a woman. My sister was in one of the dreams but she's not like that and I don't have anyone in my life who is. I'm only insecure about one relationship but that's a guy. Help.

Hi I'm new to Minecraft and was wondering if anyone could recommend some good Youtube Channels for me or give me any tips?
