Does it mean anything if a female friend starts touching you often? I can’t figure out if it is just friendly or not?

For example, walking past and brushing against you, leaning over your shoulder and having part of her body pressed against you, hands grazing yours in conversation, touching my forearm in conversation. Just generally standing really close to me when talking.
She also seeks me out a lot to talk at work and having a good laugh with me.
