Am I overthinking???

So I’m talking to this guy & things seem a little fishy for me..

Couple days ago, I had a dream that this dude who goes to my school was flirting with both, me and my mom.

I ofc didn’t think anything of it, dreams are dreams, wtv.

So, this guy I’m talking to barely knows my mom. He met her the same day me and him met up for the first time & they had a small talk but they didn’t exactly have a “bond”

So, some days ago, she asked him for money & he gave it to her..

now, today he called and asked if I wanted to go get my nails done, that he’ll come with me so I said yeah. I was cleaning at the time so I hung up quick & right after I saw that he was calling my mom’s phone. I answered for her & as soon as he heard my voice he hung up. Then, I called him from my phone and asked why he hung up & he said he wanted to tell her something. I asked what & he said “I said her not you” so he asked if she was home & I said no. I see that they have conversations on WhatsApp but she always erases the messages. Am I wrong for being suspicious?
