That would be the THC making you paranoid and dissassociated. There are varieties with less THC and more of the other cannabinoids like CBD. I don't smoke mine. I make an herbal tincture using grain alcohol and water, from the varieties I can find with the least THC. They still have more THC than I would like and I will be growing my own from a variety with less THC and more of the other cannabinoids. The THC doesn't make me paranoid or anxious but it does make me dizzy for an hour or two after I take it and I'm already suffering from ataxia so I only do mmj right before bed. I also supplement my tincture with CBD drops, which have no THC, that I get from Amazon. Probably one reason this helps me with sleep is that it helps with pain, which was making sleep impossible for me.
